Question

If Rs 800 amounts to Rs 920 in 3 years, what will Rs 900 amounts to in 4 years at the same

rate percent per annum.​

Answer 1

Answer:

Given: Principal=Rs.800,Amount=Rs.920,T=3years

Simple interest =920−800=120

∴ Rate % =

800×3

120×100

=5%

If rate % is increased by 5%, i.e., if rate % = 10%, then

SI=

100

800×3×10

=240

∴Amount=Rs.800+Rs.240=Rs.1,040
