Worked practice questions

Find the simple interest on Rs 10,000 borrowed at 15 per cent per annum for 2 years.

  1. Rs 1,500
  2. Rs 2,500
  3. Rs 3,000
  4. Rs 3,500
Show answer and solution

Correct answer: C. Rs 3,000

1. Interest for one year = (15/100) x 10000 = Rs 1,500. 2. Under simple interest the principal never changes. 3. Interest for 2 years = 1500 x 2 = Rs 3,000. 4. The amount repayable would be 10000 + 3000 = Rs 13,000. _Source: syllabus Maths Ch7 'Comparing Quantities', Example 7_

Find the simple interest on Rs 15,000 at 5 per cent per annum after 2 years.

  1. Rs 750
  2. Rs 1,750
  3. Rs 3,000
  4. Rs 1,500
Show answer and solution

Correct answer: D. Rs 1,500

1. Interest for one year = (5/100) x 15000 = Rs 750. 2. Simple interest keeps the same principal each year. 3. Interest for 2 years = 750 x 2 = Rs 1,500. 4. Amount after 2 years = 15000 + 1500 = Rs 16,500. _Source: syllabus Maths Ch7 'Comparing Quantities', TRY THESE after Example 7_

Rs 20,000 is borrowed for 2 years at 8 per cent compounded annually. What amount is repayable?

  1. Rs 23,328
  2. Rs 23,200
  3. Rs 23,128
  4. Rs 24,000
Show answer and solution

Correct answer: A. Rs 23,328

1. Interest for year 1 = (8/100) x 20000 = Rs 1,600. 2. Principal for year 2 = 20000 + 1600 = Rs 21,600. 3. Interest for year 2 = (8/100) x 21600 = Rs 1,728. 4. Amount at the end of year 2 = 21600 + 1728 = Rs 23,328. 5. Using the formula, 20000 x (1.08) squared gives the same Rs 23,328. _Source: syllabus Maths Ch7 'Comparing Quantities', section 7.4_
