Question

the difference between the compound interest and simple interest on a certain sum for 2 years at 7.5 % per annum is rupees 360 find the sum ​

Answer 1

Given

Rate of interst =7.5%

Time = 2years

Difference between Ci and si = 360

Let sum = 100

Si = 100×7.5×2/100

Si = 15

A = p(1+r/100)^t

A = 100(1+7.5/100)²

A = 100(1075/100)²

A =115.56

Ci = A-p

= 115.56-100

= 15.56

Difference between Ci and Si = 15.56-15

= 0.5625

According to the question it is 360

So,1 unit assumed = 360/0.5625

= 640

Then sum = 100×640

= 64000
