A certain sum of money amounts to 1344 Rs. in 3 years and 1440 Rs. in 5 years. Find the sum and rate of interest.​

Answer 1

Answer:

let the amount be A

let the rate be B

1344=A............1

1440=B.............2

dividing 2 by 1

1440/1344 =[1+r]^2

=1+r=1440/1344

=1.0743

1+r=1.035

sum is 1212.230

therefore rate of interest=3.5 %
