Question

in what time will the simple interest on a certain sum of money at 6(1/4)%per annum be 3/8 of itself? ​

Answer 1

Let, principal be ₹100

S.I should be 3/4th of the principal = (100 × 3/4) = {100/4=25 (3)} = 75

So,

P=₹100 R=6% T=?(x) S.I = ₹75

S.I= (p×r×t / 100)

75 = 100 × 6 × x / 100

75×100 / 100 × 6 = x

25/2 = x
