Question

In how many years does the sum of * 1200
become 1800 at the rate of simple interest of
5% per annum?​

Answer 1

Time=10 years

amount = principal + simple interest

1800 = 1200 + simple interest

simple interest = 1800 - 1200

simple interest = 600

SI=PTR/100

600 =1200*T*5/100

600 =60T

T. =10 years Ans
