Question

10800×9/8×9/8×9/8 per annum copounded annualy

Answer 1

Answer: `A = P(1+(R)/(100))^t`

P = 10800, R `=12(1)/(2)%` and t = 3 years

So, `A = 10800(1+(25)/(200))^3`

`=10800(1+1/8)^3`

`=10800(9/8)^3`

`=10800xx9/8xx9/8xx9/8=15377.34`

So, Interest `= A –P`

`=15377.54-10800=4577.34`

NCERT Solutions for Class 8 Maths Chapter 8 Comparing Quantities Ex 8.3 Q1

CI = A – P = ₹ 15,377.35 – ₹ 10,800 = ₹ 4,577.35

Hence amount = ₹ 15,377.34 and CI = ₹ 4,577.34
