Answer:
Rate of interest = R = 11%
Time = 2yrs 3 months =( 2 + 3/12 ) yrs = 9/4 yrs
Amount (A1) = Rs 4491
We know that,
A = P( 1+ TR/ 100 )
4491 = P [ 1 + ( 9 × 11 ) / (4 × 100 ) ]
4491 = P ( 400 + 99 ) /400
4491 = P ( 499 /400 )
P = ( 4491 × 400 ) / 499
P = RS 3600
2 ) P = Rs 3600
R = 11 %
T = 3 Years
Amount = A2
A2 = P ( 1 + TR /100 )
= 3600 ( 1 + 3 × 11 /100 )
= 3600 ( 100 + 33 ) /100
= 3600 × 133 / 100
= Rs 4788
The sum amounts Rs 4788 in 3 years at 11 % rate.
I hope this helps you.
