A sum of money doubles itself in 8 years at simple interest. What is the rate of interest per annum?
सही उत्तर: ख) 12.5%
Doubling means SI = P in 8 years, so R = 100/8 = 12.5%. In general, the rate is 100 divided by the number of years needed to double.

Find the simple interest on Rs. 8,000 at 6% per annum for 5 years.
सही उत्तर: ग) Rs. 2,400
SI = P × R × T/100 = 8,000 × 6 × 5/100 = Rs. 2,400. Simple interest is the same every year (Rs. 480 here).

A shopkeeper marks goods 25% above cost price and allows a discount of 10%. What is his profit percent?
सही उत्तर: क) 12.5%
Take CP = 100. MP = 125 and SP = 125 × 0.9 = 112.5, so profit = 12.5%. Subtracting 10 from 25 (15%) is wrong, because the discount is on the marked price.

An article sold for Rs. 1,150 gives a profit of 15%. At what price should it be sold to gain 25%?
सही उत्तर: घ) Rs. 1,250
CP = 1,150 ÷ 1.15 = Rs. 1,000. SP for 25% gain = 1,000 × 1.25 = Rs. 1,250.

A dishonest shopkeeper sells goods at cost price but uses a 900 g weight instead of 1 kg. What is his gain percent?
सही उत्तर: ग) 11.11%
Gain% = error/(true value − error) × 100 = 100/900 × 100 = 11.11%. 10% is wrong because the gain is on the 900 g actually given.

A trader sells two articles at Rs. 990 each, gaining 10% on one and losing 10% on the other. What is the overall result?
सही उत्तर: ख) Loss of 1%
When two items are sold at the same SP with x% gain and x% loss, there is always a loss of x²/100% = 1%. Here the CPs are 900 and 1,100, total 2,000, and the total SP is 1,980.

If the cost price of 12 articles equals the selling price of 10 articles, what is the profit percent?
सही उत्तर: ग) 20%
Let CP of 1 article = Re 1. SP of 10 = 12, so profit = 2 on a cost of 10, which is 20%. 16.67% comes from wrongly dividing by 12.

An article marked at Rs. 2,000 is sold at a 15% discount and still the seller gains 25%. What is its cost price?
सही उत्तर: क) Rs. 1,360
SP = 2,000 × 0.85 = Rs. 1,700. CP = 1,700 ÷ 1.25 = Rs. 1,360.

By selling an article for Rs. 1,080, a shopkeeper gains 20%. What is the cost price?
सही उत्तर: घ) Rs. 900
CP = 1,080 ÷ 1.20 = Rs. 900. Taking 20% off 1,080 (Rs. 864) is wrong, because profit percent is calculated on cost price.
