Question

if the compound interest on a certain dum for 2 years at the rate of 10% p.a. is Rs 630%/- the sum is​

Answer 1

Answer:

Amount after t years, when interest is compounded annually =

(P(1+R/100)t)

Let the sum be Rs. y. Then,

(y(1+10/100)2−y=630

)

By solving, we get

Sum, y = Rs. 3000

S.I. =(P×R×T100)

S.I.

=3000×10×3100=Rs. 900
