Question

in what time will Rs. 2750 amounts to Rd. 3575, if simple interest rate is calculated at 10% per annum?

Answer 1

Given,

Principle (P) = Rs. 2750

Amount (A) = Rs. 3575

Rate (R) = 10%p.a.

∴ S.I. = A-P

         = Rs. 3575-2750

         = Rs. 825

T = S.I.× 100  ÷  P×R

  = 825×100 ÷ 2750×10

  = 82500 ÷ 27500

T = 3 years

Hence, Time = 3 years

Answer 2

if,
Principle=2750
Amount=3575
Rate=10%
then,
A=P+SI
SI=A-P
SI=3575-2750
SI=825
T=SI x 100/P x R
T=82500/27500
T=3years
