Amit is ﬁve years older than Vaibhav at present. After four years the ratio of their ages will be 5 ∶ 4. What is Amit's age (in years) at present?
Let Vaibhav’s age = a and Amit’s age = 5 + a
(Amit's age after 4 years)/(Vaibhav's age after 4 years) = 5/4
⇒ (5 + a + 4)/(a + 4) = 5/4
⇒ 20 + 4a + 16 = 5a + 20
⇒ 5a – 4a = 16
⇒ a = 16
∴ Amit’s age = 5 + a = 5 + 16 = 21
A man spends 80% of his income and saves the rest. If his income and spending both increases by 10%, then what is the percentage change in his savings?
Let,
Income of the man in Rs. = x
He spends 80%
∴ Amount of spend in Rs. = 0.80x
∴ Amount of savings in Rs. = x  0.80x = 0.20x
If his income and spending both increases by 10%,
New amount of Income Rs. = 1.10x
New amount of spend in Rs. = (1.10) × (0.80x) = 0.88x
∴ New amount of savings in Rs. = 1.10x  0.88x = 0.22x
∴ Percentage increase in savings= [(0.22x  0.20x)/0.20x] × 100% = (0.02/0.20) × 100% = 10%
∴ 10% increase in savings.

Haemophilia is a genetic disorder which leads to ________.
Haemophilia is a frequently inherited genetic disorder that impairs the body's ability to form blood clots, a process required to stop bleeding. This results in people bleeding longer after an injury, easy bruising, and an increased risk of bleeding inside joints or the brain. Those with a mild case of the disease may have symptoms only after an accident or during surgery. Bleeding into a joint can result in permanent damage while bleeding in the brain can result in long term headaches, seizures or a decreased level of consciousness.
Divide Rs. 960 among M, N and O so that M get (3/9)th of N's share and O gets (4/7)th of M's share. What is the share (in Rs) of O?
Let the shares of M, N and O be represented by m, n and o respectively.
According to given information,
M’s share = m = 3n/9 = n/3
O’s share = o = 4m/7 = (4/7) × (n/3) = 4n/21
Ratio of their shares = m ∶ n ∶ o = (1/3) ∶ 1 ∶ (4/21) = 7 ∶ 21 ∶ 4
Share of O = 960 × [4/(7 + 21 + 4)] = Rs. 120
∴ Share of O = Rs. 120

The average marks of A, B and C is 66. When D's marks are also included, the average is increased by 4 marks. Now if A is replaced by E, the new average is reduced by 2 marks. What is the sum of marks of A and D, if E's marks are 52?
Average marks of A, B and C = 66
Total marks of A, B and C = 66 x 3 = 198
When D is included, average increases by 4 = 66 + 4 = 70
Total marks of A, B, C and D = 70 x 4 = 280
D's marks = 280  198 = 82
A is replaced by E, average reduces by 2
New average = 70  2 = 68
Total marks of E, B, C and D = 68 x 4 = 272
A's marks = 52 + 8 = 60
Sum of marks of A and D = 60 + 82 = 142
By Selling 4 articles for 1 rupee, a man losses 50%. Had he sold 2 articles per rupee, then what will be the profit percentage?

A sells vegetables at a price, 35% more than its cost price and for weighing uses a weight which is 10% less than the article weight. What is total profit percentage?
Let the cost of 1 kg vegetable = Rs. 100
But the seller sells 900 gm. Instead of 1 kg which costs Rs. 90
Given, Profit% = 35%
So, selling price = 100 + (35/100) × 100 = Rs. 135
∴ Actual profit percentage = [(135 – 90)/90] × 100 = 50%
Which among these language translators that can convert high level language program into machine language at one go.
Rs. 10000 is kept at compound interest rate of 18% per annum (compounding annually). If the compounding of interest is done half yearly, then how much more interest (in Rs) will be obtained?
When compounded yearly,
Compounded amount = principal {1 + (rate/100)} = 10000{1 + (18/100)} = 11800
Compound interest = Amount  principal = 11800  10000 = Rs. 1800
When compounded half yearly,
⇒ Rate = 18/2 = 9%
⇒ Time = 2 × 1 = 2
⇒ Compounded amount = principal {1 + (rate/100)} ^{time} = 10000{1 + (9/100)}^{2} = 11881
⇒ Compound interest = Amount  Principal = 11881  10000 = Rs. 1881
∴ Required difference = 1881  1800 = Rs. 81
What is the name of India’s first RoboCop introduced in the Kerala Police Headquarters?
x^{3} + y^{3} = 22 and x + y = 5 then find the approximate value of x^{4} + y^{4}.
We know that
x^{3} + y^{3} = (x + y)(x^{2} + y^{2} – xy)
Now we have x^{3} + y^{3} = 22 and x + y = 5
⇒ 22 = 5(x^{2} + y^{2} – xy)
⇒ 22 = 5[(x + y)^{2} − 3xy)]
⇒ 22 = 5[(5)^{2} − 3xy)]
⇒ xy = 103/15
Now multiply x^{3} + y^{3} = 22 with x + y = 5
⇒ x^{4} + y^{4} + xy(x^{2} + y^{2}) = 110
⇒ x^{4} + y^{4 }= 110 – xy{(x^{2} + y^{2 }− 2xy + 2xy)}
⇒ x^{4} + y^{4 }= 110 – xy{(x + y)^{2 }− 2xy}
xy = 103/15 and x + y = 5
⇒ x^{4} + y^{4 }= 110 – 103/15{(5)^{2 }− 2 × 103/15}
⇒ x^{4} + y^{4 }= 110 – 6.87{(25 – 13.73}
⇒ x4 + y4 = 110 – 6.87 {(11.27)}
⇒ x^{4} + y^{4 }= 110 – 77.42
⇒ x4 + y4 = 32.58
∴ Value of x^{4} + y^{4 }is 33.

This means calendar of 2024 is similar to that of 2018. But this is not possible as 2024 is a leap year but 2018 is an ordinary year.
Number of odd days from 2018 till 2024 = 0 + 2 = 2
Number of odd days from 2018 till 2025 = 2 + 1 = 3
Number of odd days from 2018 till 2026 = 3 + 1 = 4
Number of odd days from 2018 till 2027 = 4 + 1 = 5
Number of odd days from 2018 till 2028 = 5 + 2 = 7 = 0 odd days
Hence, calendar of 2029 will be similar to that of 2018.

Which of the following process is used to strengthen the glass?
P is four times as efficient as Q. P can complete a work in 45 days less than Q. If both of them work together, then in how many days the work will be completed?
Let efficiency of Q be q.
⇒ Efficiency of P = 4q.
Time taken by Q = 1/q
Time taken by P = 1/4q
P can complete a work in 45 days less than Q
⇒ 1/4q = 1/q  45
3/4q = 45
q = 3/45 = 1/60
Combined efficiency = q + 4q = 5q.
Time taken by them together = 1/5q = 1/(5 × 1/60) = 12 days.
A merchant purchases a watch for Rs 540 and fixes its marked price in such a way that after allowing a discount of 10%, he earns a profit of 35%. What is the marked price (in Rs) of the watch?
Let the MP = x
⇒ CP = 540 (Given)
SP = x  0.1x = 0.9x
Profit = 35%
⇒ (SP  CP)/CP = 0.35
⇒ (0.9x  540)/540 = 0.35
⇒ 0.9x  540 = 189
⇒ 0.9x = 729
⇒ x = 729/0.9 = 810
∴ MP = Rs. 810
Alternative Method:
Relationship between CP and MP
CP : MP = (100  D%) : (100 + P%)
CP : MP = (100  10) : (100 + 35) = 2 : 3
2 unit = 540
∴ 3 units = 810
What is the least number which when increased by 23 is divisible by each of 42, 36 and 45?
LCM of 42, 36 and 45 = 1260
This is the least number which will be divisible by 42, 36 and 45.
∴ The least number which when added by 23 will be divisible by 42, 36 and 45 = 1260 – 23 = 1237

Q. What was the total expenditure (in Rs. crores) of the company Q, R and T together?
Total expenditure = 48 crores
Expenditure of company Q, R and T together = (22 + 18 + 20)% of total expenditure
Expenditure of company Q, R and T together = 60% of 48
∴ Expenditure of company Q, R and T together = 28.8 crores
Direction: The following pie chart shows the expenditure (in percentage) of five companies P, Q, R, S and T in the year 2016. Total Expenditure = Rs. 48 crores
Q. By how much percent expenditure of company Q and R together greater than that of company P?
Total expenditure = 48 crores
Expenditure of company Q and R = (22 + 18)% of total expenditure
Expenditure of company Q and R = 40% of 48 = 19.2
Expenditure of company P = 24% of 48 = 11.52
Percentage of expenditure of Q and R greater in terms of P = (19.2  11.52/11.52) × 100
∴ Percentage = 66.67 %
Direction: The following pie chart shows the expenditure (in percentage) of five companies P, Q, R, S and T in the year 2016. Total Expenditure = Rs. 48 crores
Q. What is the respective ratio between the total expenditure of company P, Q and S together to the total expenditure?
