Rupees 1,080 invested for 3 months gave an interest of Rupees 27. What was the simple rate of interest per annum?

  1. 2.5%
  2. 10%
  3. 5%
  4. 7.5%
Show answer and solution

Correct answer: B. 10%

1. SI = (P x R x T)/100, with T = 3 months = 3/12 year. 2. 27 = (1080 x R x 3/12)/100 = (1080 x 3 x R)/1200. 3. 27 = 270R/100, so R = 2700/270 = 10%. _Source: RRB Group D CEN-02/2018 PYQ, Q.7._

Raghu invested ₹1000 and received ₹1300 at 6% per annum simple interest after X years. Find X.

  1. 4 years
  2. 3 years
  3. 2 years
  4. 5 years
Show answer and solution

Correct answer: D. 5 years

1. Interest earned = 1300 − 1000 = ₹300. 2. SI = P × R × T / 100, so 300 = 1000 × 6 × X / 100 = 60X. 3. X = 300 / 60 = 5 years. _Source: RRB Group D CEN-02/2018 PYQ, Q.28._
