Sample questions with solutions
A few questions like the ones in this test, with the right answer and why.
- Question 1A farmer harvested 720 kg of wheat and kept 45% of it for his family. How many kg of wheat did he keep for his family?
- 396 kg
- 324 kgRight answer
- 32.4 kg
- 16 kg
ExplanationMultiply by the percentage and divide by 100: 720 × 45 ÷ 100 = 324.
Shortcut: 45% = 50% − 5%. 50% of 720 = 360, and 5% is a tenth of that, 36. So 45% = 360 − 36 = 324.
So he kept 324 kg of wheat for his family. - Question 2In a village, 7 out of every 12 people are farmers. What percent of the people of the village are farmers?
- 84%
- 41⅔%
- 56%
- 58⅓%Right answer
Explanation7 out of 12 is the fraction 7/12. Multiply by 100: 7/12 × 100 = 700 ÷ 12, which is 58⅓. So 58⅓% of the people are farmers.
Shortcut: 7/12 = 6/12 + 1/12 = 1/2 + 1/12. Here 1/2 is 50%, and 1/12 is 8⅓%, half of 1/6 (16⅔%). So 7/12 is 50% plus 8⅓%, that is 58⅓%.
Check: in a village of 1,200 people, 7/12 of 1,200 is 700 farmers, and 700 ÷ 1,200 × 100 = 58.33, that is 58⅓%. - Question 32.5 quintals of wheat were stored in a godown, and 15 kg of it got spoiled. What percent of the stored wheat got spoiled?
- 6%Right answer
- 0.6%
- 600%
- 94%
Explanation1 quintal = 100 kg, so 2.5 quintals = 2.5 × 100 = 250 kg.
Spoiled share = 15 ÷ 250 × 100 = 6, so 6% of the wheat got spoiled.
Shortcut: 1% of 250 kg is 2.5 kg, and 15 ÷ 2.5 = 6, so 15 kg is 6%. - Question 4The population of a village is 12,400. It grows by 5% in one year. What will the population of the village be after one year?
- 620
- 12,462
- 13,020Right answer
- 11,780
Explanation5% of 12,400 = 620 (10% is 1,240, and 5% is half of that).
Population after one year = 12,400 + 620 = 13,020.
Shortcut (multiplier): growing by 5% means multiplying by 1.05, and 12,400 × 1.05 = 13,020. - Question 5The price of onions rose from ₹35 per kg to ₹70 per kg. By what percent did the price rise?
- 200%
- 100%Right answer
- 50%
- 35%
ExplanationRise = 70 − 35 = ₹35.
Percent rise = 35 ÷ 35 × 100 = 100, so the price rose by 100%.
Shortcut: the price doubled. Doubling means the rise equals the old price, which is a 100% rise; the new price is 200% of the old one.
Check: 100% of 35 = 35, and 35 + 35 = 70.
