Question

find the sum which will amount to ₹ 700 in 5 years at 8% per annum

Answer 1

Amount is rs 700
time is 5 years
rate is 8%pa

let the principal be rs 100
Then SI=PRT/100
100×8×5/100=rs 40
Amount = P+SI=rs (100+40)=rs 140

ATQ,
if amount is rs 140, then principal is rs 100
if amount is rs 1, then the principal is rs 100/140
if the amount is rs 700, then the principal is rs 100/140×700=rs 500
Thus, the sum is rs 500
