Q. What were the total runs scored in 2016?

Detailed Solution for MCQ Test: Caselets - 1 - Question 1

2015: 
The total runs scored in 2015 were 1200. 
The average runs scored against Australia and England was 300 so the total runs scored against Australia and England was 600. 
The total runs scored against others = 1200 – 600 = 600 
 
2016: 
The ratio of the total runs scored against Others in 2015 to that of the total runs scored against Others in 2016 is 4 : 3.  
So the total runs against Others in 2016
= 600/4 × 3 = 450
The total runs scored against Australia and Others = 1200 
The total runs scored against Australia = 1200 – 450 = 750 
 
2017: 
The total runs scored in 2017 were 1400. 
The sum of the total runs scored against Australia and England is equal to the total runs scored against Others. It means the total runs scored against Others were is half i.e 700 runs and the sum of the total runs scored against Australia and England was 700. 

2015:
The runs scored against England were 1/3rd of the runs against Others in 2016.
So the total runs scored against England were  
= 450/3 = 150
The total runs scored against Australia = 600 – 150 = 450

2017:
The total runs scored against Australia were twice of the runs scored against England in 2015.
The total runs scored against Australia = 150 × 2= 300
The total runs scored against England = 700 – 300=400

2016:
The total runs scored against England in 2016 were equal to the total runs scored against England in 2017.
The total runs scored against England = 400

The total runs scored in 2016 were 1600.

MCQ Test: Caselets - 1 - Question 6

Directions: Study the following caselet carefully to answer the questions given beside.
Rahim is an employee in TCS. In December 2019, his expenditure and savings are as follows:
He spends four times on house rent of what he spends on grocery in that month. One-fifth of his salary goes on these two items only. He spends a total of Rs. 10000 on school fee of his kids and house maid. He also gives Rs. 12000 to his younger brother who studies in college, which is thrice the amount he gives to house maid. Expenditure on petrol is Rs. 6000, and two-third of expenditure on petrol is equal to the expenditure on grocery. He also goes to the gym for which he pays half what he pays to his house maid. Whatever left after all this expenditure becomes his savings for December 2019.

Q. In January 2020, his younger brother earns some money through a part time work at college so now he takes only Rs. 8000 in that month from Rahim. What is the savings of Rahim in January 2020?

Detailed Solution for MCQ Test: Caselets - 1 - Question 6

His brother was earlier taking Rs. 12000 and now Rs. 8000, so Rahim now would save Rs. 4000. In his total savings of Rs. 50000 that we evaluated in common explanation, he would have Rs. (50000 + 4000) = Rs. 54000.
Hence, option B is correct.
 
Common Explanation:

Expenditure on petrol is Rs. 6000, and since two-third of expenditure on petrol is equal to expenditure on grocery, we have
Expenditure on grocery is (2 / 3) × 6000 = Rs. 4000
He spend four times on house rent on what he spend on grocery in that month, means
Expenditure on house rent = 4 × 4000 = Rs. 16000
Expenditure on grocery + house rent = 4000 + 16000 = 20000
This is one-fifth of his salary, means his salary is = 5 × 20000 = Rs. 100000
He gives Rs. 12000 to his younger brother, which is thrice the amount he gives to house maid, means
Expenditure on house maid = Rs. (1 / 3) × 12000 = Rs. 4000
Expenditure on school fee + house maid = 10000
Expenditure on school fee + 4000 = 10000
Expenditure on school fee = Rs. 6000
He go to gym for which he pays half what he pays to his house maid = (1 / 2) × 4000 = Rs. 2000
We tabulate all this information as follows:

MCQ Test: Caselets - 1 - Question 7

Directions: Study the following caselet carefully to answer the questions given beside.
Rahim is an employee in TCS. In December 2019, his expenditure and savings are as follows:
He spends four times on house rent of what he spends on grocery in that month. One-fifth of his salary goes on these two items only. He spends a total of Rs. 10000 on school fee of his kids and house maid. He also gives Rs. 12000 to his younger brother who studies in college, which is thrice the amount he gives to house maid. Expenditure on petrol is Rs. 6000, and two-third of expenditure on petrol is equal to the expenditure on grocery. He also goes to the gym for which he pays half what he pays to his house maid. Whatever left after all this expenditure becomes his savings for December 2019.

Q. If the expenditure in December 2019 was same for each month of the year 2019 and in the year 2019 he has to pay 15% income tax on total annual income, then what average amount he would have saved each month in the year 2019?

Detailed Solution for MCQ Test: Caselets - 1 - Question 7

Total annual income = Rs. 100000 × 12
Income tax = 15% of Rs. 100000 × 12
Total savings in a month = Rs. 50000
Total savings in 2019 = Rs. 50000 x 12 (this include income tax yet to be paid)
After removing income tax he would save = Rs. 50000 × 12 – 15% of Rs. 100000 × 12 = 420000
Monthly average savings = 420000 / 12 = Rs. 35000
Hence, option A is correct.

Common Explanation:
Expenditure on petrol is Rs. 6000, and since two-third of expenditure on petrol is equal to expenditure on grocery, we have
Expenditure on grocery is (2 / 3) × 6000 = Rs. 4000
He spend four times on house rent on what he spend on grocery in that month, means
Expenditure on house rent = 4 × 4000 = Rs. 16000
Expenditure on grocery + house rent = 4000 + 16000 = 20000
This is one-fifth of his salary, means his salary is = 5 × 20000 = Rs. 100000
He gives Rs. 12000 to his younger brother, which is thrice the amount he gives to house maid, means
Expenditure on house maid = Rs. (1 / 3) × 12000 = Rs. 4000
Expenditure on school fee + house maid = 10000
Expenditure on school fee + 4000 = 10000
Expenditure on school fee = Rs. 6000
He go to gym for which he pays half what he pays to his house maid = (1 / 2) × 4000 = Rs. 2000
We tabulate all this information as follows:

MCQ Test: Caselets - 1 - Question 8

Directions: Study the following caselet carefully to answer the questions given beside.
Rahim is an employee in TCS. In December 2019, his expenditure and savings are as follows:
He spends four times on house rent of what he spends on grocery in that month. One-fifth of his salary goes on these two items only. He spends a total of Rs. 10000 on school fee of his kids and house maid. He also gives Rs. 12000 to his younger brother who studies in college, which is thrice the amount he gives to house maid. Expenditure on petrol is Rs. 6000, and two-third of expenditure on petrol is equal to the expenditure on grocery. He also goes to the gym for which he pays half what he pays to his house maid. Whatever left after all this expenditure becomes his savings for December 2019.

Q. Rahim’s one of the friends Shyam also works at the same position and gets a salary equal to Rahim. Shyam has no kids and he has no younger brother like Rahim but Shyam sends Rs. 15000 to his parents each month. All other expenses of Shyam are the same as Rahim’s. In December 2019, what percent more/less Shyam saves each month than Rahim?

Detailed Solution for MCQ Test: Caselets - 1 - Question 8

Rahim’s monthly savings in December 2019 were Rs. 50000.
Shyam’s expenses are similar to Rahim’s except for two things.
Shyam has no kids, so no school fee, thus his savings = 50000 + 6000
Shyam send Rs. 15000 to his parents, but he doesn’t have to send Rs. 12000 to his brother like Rahim send, so Shyam here has to spend Rs. 3000 more.
So, Shyam savings due to this thing would become 50000 + 6000 – 3000 = Rs. 53000.
So Shyam’s savings are Rs. 3000 more than Rahim’s. In percentage, it becomes
3000 / 50000 × 100 = 6%
Hence, option C is correct.

Common Explanation:
Expenditure on petrol is Rs. 6000, and since two-third of expenditure on petrol is equal to expenditure on grocery, we have
Expenditure on grocery is (2 / 3) × 6000 = Rs. 4000
He spend four times on house rent on what he spend on grocery in that month, means
Expenditure on house rent = 4 × 4000 = Rs. 16000
Expenditure on grocery + house rent = 4000 + 16000 = 20000
This is one-fifth of his salary, means his salary is = 5 × 20000 = Rs. 100000
He gives Rs. 12000 to his younger brother, which is thrice the amount he gives to house maid, means
Expenditure on house maid = Rs. (1 / 3) × 12000 = Rs. 4000
Expenditure on school fee + house maid = 10000
Expenditure on school fee + 4000 = 10000
Expenditure on school fee = Rs. 6000
He go to gym for which he pays half what he pays to his house maid = (1 / 2) × 4000 = Rs. 2000
We tabulate all this information as follows:

He spends four times on house rent of what he spends on grocery in that month. One-fifth of his salary goes on these two items only. He spends a total of Rs. 10000 on school fee of his kids and house maid. He also gives Rs. 12000 to his younger brother who studies in college, which is thrice the amount he gives to house maid. Expenditure on petrol is Rs. 6000, and two-third of expenditure on petrol is equal to the expenditure on grocery. He also goes to the gym for which he pays half what he pays to his house maid. Whatever left after all this expenditure becomes his savings for December 2019.

Q. Which of the following set contributes to the maximum expenditure?

Detailed Solution for MCQ Test: Caselets - 1 - Question 9

We check each option one by one as follows.
(A) (Grocery = 4000) + (house maid = 4000) + (petrol = 6000) = 14000
(B) (Gym = 2000) + (school fee = 6000) + (Grocery = 4000) = 12000
(C) (Petrol = 6000) + (Gym = 2000) + (house maid = 4000) = 12000
(D) (school fee = 6000) + (petrol = 6000) + (Grocery = 4000) = 16000
Hence, option D is correct.

Common Explanation:
Expenditure on petrol is Rs. 6000, and since two-third of expenditure on petrol is equal to expenditure on grocery, we have
Expenditure on grocery is (2 / 3) × 6000 = Rs. 4000
He spend four times on house rent on what he spend on grocery in that month, means
Expenditure on house rent = 4 × 4000 = Rs. 16000
Expenditure on grocery + house rent = 4000 + 16000 = 20000
This is one-fifth of his salary, means his salary is = 5 × 20000 = Rs. 100000
He gives Rs. 12000 to his younger brother, which is thrice the amount he gives to house maid, means
Expenditure on house maid = Rs. (1 / 3) × 12000 = Rs. 4000
Expenditure on school fee + house maid = 10000
Expenditure on school fee + 4000 = 10000
Expenditure on school fee = Rs. 6000
He go to gym for which he pays half what he pays to his house maid = (1 / 2) × 4000 = Rs. 2000
We tabulate all this information as follows:

Q. All his savings he made in the year 2021 he deposited in a bank on 1st January 2022, and similarly the savings in the year 2022, he deposited in the bank on 1st January 2023, both at 5% simple interest. If he withdraws all his money on 1st January 2024, what total amount as interest he will get from the bank? [Assuming his monthly savings remains the same as it was in December 2019]

Detailed Solution for MCQ Test: Caselets - 1 - Question 10

Savings in the year 2021 = Rs. 50000 × 12
He put this amount at 5% SI for 2 years.
SI he will get on this = (Rs. 50000 × 12) × 5 × 2 / 100 = 5000 × 12 = 60000
Savings in the year 2022 = Rs. 50000 × 12
He put this amount at 5% SI for 1 year.
SI he will get on this = (Rs. 50000 × 12) × 5 × 1 / 100 = 5000 × 6 = 30000
Total amount = 60000 + 30000 = Rs. 90000
Hence, option C is correct.

Common Explanation:
Expenditure on petrol is Rs. 6000, and since two-third of expenditure on petrol is equal to expenditure on grocery, we have
Expenditure on grocery is (2 / 3) × 6000 = Rs. 4000
He spend four times on house rent on what he spend on grocery in that month, means
Expenditure on house rent = 4 × 4000 = Rs. 16000
Expenditure on grocery + house rent = 4000 + 16000 = 20000
This is one-fifth of his salary, means his salary is = 5 × 20000 = Rs. 100000
He gives Rs. 12000 to his younger brother, which is thrice the amount he gives to house maid, means
Expenditure on house maid = Rs. (1 / 3) × 12000 = Rs. 4000
Expenditure on school fee + house maid = 10000
Expenditure on school fee + 4000 = 10000
Expenditure on school fee = Rs. 6000
He go to gym for which he pays half what he pays to his house maid = (1 / 2) × 4000 = Rs. 2000
We tabulate all this information as follows:
