Free General Awareness Mock Test 10 Questions 10 Marks 10 Mins Given: S.I = 4P/5 Rate(R) = 20% Formula used: Simple Interest = (Principal × Rate × Time)/100 Calculation: Let the time be x years and the sum of money be Rs. P Simple Interest = (Principal × Rate × Time)/100 ⇒ Simple Interest = (P × 20 × x)/100 ⇒ (4/5) × P = (P × 20 × x)/100 ⇒ x = 4 ∴ The required time is 4 years.

Given that sum of money at 6% be 5/8 of itself. Therefore, S.I = 5x / 8. T = (S.I × 100) / P × R. That is 10 years and 5 months.
In what time will the interest on a certain sum of money at 7% be of itself?I = Ptr/100,
where r = rate of interest p.a. Therefore the time of investment is 25 years.
