A sum earns Rs 900 simple interest in 3 years at 6% per annum. The principal is:
सही उत्तर: ग) Rs 5,000
P = SI × 100/(T × R) = 900 × 100 / 18 = Rs 5,000. Check: 5,000 × 3 × 6/100 = 900.

At what rate of simple interest will Rs 4,000 earn Rs 600 in 3 years?
सही उत्तर: ख) 5% per annum
R = (SI × 100)/(P × T) = 600 × 100 / (4,000 × 3) = 5%. 15% is the total interest percent over 3 years, not per year.

Express 3/8 as a percentage.

A price is first increased by 10% and then decreased by 10%. The net change is:
सही उत्तर: ग) 1% decrease
Net factor = 1.10 × 0.90 = 0.99, i.e. a 1% decrease. It is not 'no change' because the 10% decrease is taken on a larger amount.

The price of an item including 13% VAT is Rs 1,130. The price before VAT is:
सही उत्तर: ख) Rs 1,000
Price with VAT = 1.13 × original, so original = 1,130 ÷ 1.13 = Rs 1,000. Subtracting 13% of 1,130 (giving Rs 983.10) is a common mistake.

A shopkeeper buys an item for Rs 400 and wants a 25% profit. The selling price should be:
सही उत्तर: क) Rs 500
SP = CP × (1 + 25/100) = 400 × 1.25 = Rs 500. Rs 425 adds only Rs 25 instead of 25%.

A watch bought for Rs 800 is sold for Rs 720. The loss percent is:
सही उत्तर: घ) 10%
Loss = Rs 80; loss % = 80/800 × 100 = 10%. 11.11% comes from dividing by the selling price, which is incorrect.

An article bought for Rs 500 is sold for Rs 600. The profit percent is:
सही उत्तर: ग) 20%
Profit = Rs 100; profit % = 100/500 × 100 = 20% (always on cost price). 16.67% is obtained wrongly by dividing by the selling price.
