Q: What will be the percentage of increase in salary from Rs. 4,000 to Rs. 4,600?

Correct Answer: 15% - The increase is ₹600 on a base of ₹4,000; percentage increase = (600/4000) × 100 = 15%.

Q: A person divided his property among his only son and two daughters in the ratio 2:1:1. If the son's share is Rs. 60,000, what is the total value of the property?

Correct Answer: Rs. 1,20,000 - The ratio has 4 total parts. The son's 2 parts equal ₹60,000, so 1 part = ₹30,000 and the total = 4 × ₹30,000 = ₹1,20,000.

Q: The average age of 40 employees in a company is 25 years. If a new employee is included, the average increases by 3 months. What is the age of the new employee?

Correct Answer: 35 years 3 months - The old total age is 40 × 25 = 1,000 years. The new average is 25.25 years, giving a new total of 41 × 25.25 = 1,035.25 years; the new employee is 35.25 years old.

Q: At what rate per annum simple interest will a certain sum of money become double in 10 years?

Correct Answer: 10% - For a sum to double under simple interest, interest equals principal. Using SI = (P × R × T)/100, R = 100/10 = 10% per annum.

Q: Rohan purchased a TV set for Rs. 4,500 and sold it to Raj at a profit of 10%. Raj later sold it back to Rohan at a loss of 10%. Find Rohan's net gain on the whole transaction.
