• Numerical Ability - Interest
Question

A lent Rs. 5000 to B for 2 years and Rs. 3000 to C for 4 years on simple interest at the same rate of interest and received Rs. 2200 in all from both of them as interest. The rate of interest per annum is:

  • A) 5%
  • B) 7%
  • C) 11%
  • D) 10%
  • E) None of these
Solution

(d);

5000×r×2 / 100 + 3000×4×r / 100 = 2200
22000r = 22000 × 10
r = 10%

(d);

5000×r×2 / 100 + 3000×4×r / 100 = 2200
22000r = 22000 × 10
r = 10%
