Question

A sum of money at simple interest amount
to be * 1260 in 2 yr and * 1350 in 5 yr,
then the rate per cent per annum is
(a) 30% (b) 10% (c) 2.5% (d) 5%​

Answer 1

Answer:

(c) 2.5% per annum

Step-by-step explanation:

S.I for 3 years = Rs. (1350 - 1260) = Rs. 90

S.I for 2 years = Rs.(90/3) x 2 = Rs. 60

Since, Sum = Rs. (1260 - 60) = Rs. 1200

Therefore, Rate = (100 x SI) / (P x T) = (100 x 60) /

(1200 x 2) = 2.5%
