Question

Devesh gave Manav rupees 1250 on compound interest of 2 years at the rate of 12% per annum how much less would Devesh have got had he given the money to Manav for 2 years on the simple interest at the rate of 4% per annum​

Answer 1

Answer:

Rs 108

Step-by-step explanation:

Case I : Compound Interest

Principle (P)= Rs 1250

Rate of interest (R) = 12 % / annum

Time (T) = 2 yrs

A = P(1 + R/100)^T

A = 1250( 1 + 3/25)^2

A = 1250 * 27/25 *  27/25

A = Rs 1458

C.I. = A -- P

C.I. = 1458 -- 1250

     = Rs 208

Case II : Simple Interest

Principle (P) = Rs 1250

Rate of interest (R) = 4 % / annum

Time (T) = 2 yrs

S.I. = PRT/100

S.I. = 1250 X 4 X 2/100

     = Rs 100

∴ Devesh would have got Rs (208 -- 100) = Rs 108 less.

Answer 2

Answer:

Step-by-step explanation:

First find compound interest

=>P=1250

=>R=12% per annum

=>T=2 YEARS

=>P(1+R/100)=1250(1+12/100)²

=>1250×25/28×25/28

=>1568-1250=0318

Now find simple interest:-

P×R×T/100

=>1250×4×2/100

=>100-318

=>218

He would get get 218 less

=>
