Question

. In how many years will Rs. 25,000 invested at 8% per annum
amount to Rs. 33,000?

Answer 1

Principal =25000
rate= 8%
amount =33000
let years be t.
so , s.i = amount -Principal
= 33000-25000
= 8000
now,
s.i = prt/ 100
8000= 25000 × 8 × t / 100
so, t = 8000× 100 / 25000 × 8
t = 4
so, years = 4 ans.
