Total work = LCM {6,8} = 24 units
Number of units of work done by Amit in 1 hour = 24/6 = 4 units
Number of units of work done by Amit in 2 hours = 4 × 2 = 8 units
Work left = (24 – 8) = 16 units

Directions: The following caselet shows the number of males and females working in three different hospitals.

Number of females working in hospital A is 40% more than the number of males working in the same hospital and the number of males working in hospital B is 100 less than the males working in hospital A. Number of females working in hospital B is  100 less than the number of females working in hospital A. Number females working in hospital C is 75% of the number of females working in hospital B. Total females working in all the hospitals is 1750. Ratio between the number of females to males in hospital C is 3: 2.

If 66.66% of the males working in hospital C are married and 40% of the females working in hospital C are unmarried. Find the number of married persons working in hospital C.
Detailed Solution for Test: Data Caselets - Question 6

Test: Data Caselets - Question 9
Save

Direction: Read the following data carefully and answer the following questions :

Two friends Amy and Sammy invested different amounts on simple and compound interest. The difference between the amount invested on simple interest by Sammy and Amy is Rs. 6000 and total simple interest earned by Amy and Sammy is Rs. 20640. Total amount invested in compound interest by Amy and Sammy is Rs. 25000 and the ratio between the amount invested on compound interest by Sammy and Amy is 3 : 2. Amy and Sammy invested on simple interest at the rate of interest 20% and 24% for 5 and 2 years respectively. For compound interest, Amy and Sammy invested at the rate of interest of 10% and 20% for two years and a year respectively.

What percent is the total sum invested by Amy and Sammy on the compound interest of the total sum invested on simple interest? (Sammy's investment is more than that of Amy's investment).
Detailed Solution for Test: Data Caselets - Question 9

Let amounts invested by Amy and Sammy on compound interest be Rs. A and Rs. B respectively.

⇒ A + B = 25000

⇒ B : A = 3 : 2

⇒ B = 3A/2

Solving,

⇒ A + 3A/2 = 25000

A = Rs. 10000 and B = Rs. 15000

Total sum invested by Amy and Sammy on compound interest = 10000 + 15000 = Rs. 25000

Let the amount invested by Amy and Sammy on simple interest be Rs. M and Rs. (6000 + M) respectively.

Simple Interest earned by Amy = M × 5 × 20/100 = M

Simple Interest earned by Sammy = (6000 + M) × 24 × 2/100 = 2880 + 12M/25

⇒ M + 2880 + 12M/25 = 20640

⇒ M = Rs. 12000

Amount invested by Amy = Rs. 12000

Amount invested by Sammy = 12000 + 6000 = Rs. 18000

Total sum invested by Amy and Sammy on simple interest = 12000 + 18000 = Rs. 30000

Required percentage = 25000/30000 × 100

∴ Required percentage = 83.33%

Direction: Read the following data carefully and answer the following questions :

Amy and Sammy invested on simple interest at the rate of interest 20% and 24% for 5 and 2 years respectively. For compound interest, Amy and Sammy invested at the rate of interest of 10% and 20% for two years and a year respectively.

What is the ratio between the amounts got after 2 years and a year on the sum invested by Amy and Sammy on compound interest calculated annually?
Detailed Solution for Test: Data Caselets - Question 10

Let amounts invested by Amy and Sammy on compound interest be Rs. A and Rs. B respectively.

⇒ A + B = 25000

⇒ B : A = 3 : 2

⇒ B = 3A/2

Solving,

⇒ A + 3A/2 = 25000

A = Rs. 10000 and B = Rs. 15000

Amount earned by Amy = 10000 × (1 + 10/100)2 = Rs. 12100

Amount earned by Sammy = 15000 × (1 + 20/100) = Rs. 18000

Required ratio = 12100 : 18000

∴ Required ratio = 121 : 180
