Question

Principle × Rate × Time = PTR/100

⇒ Simple Interest = 4000 × (7 ⁄ 100) × 2

⇒ Simple Interest = 560

∴ The simple Interest for 2 years is Rs. 560

Compound Interest = Principal × (1 + Rate)Time − Principal

So, Compound Interest = 4000 × (1 + 7 ⁄ 100)2 − 4000

⇒ Compound Interest = (4000 × 1.1449) − 4000
is_______please calculate

P=4000

R=10%

Times =2.5 years

First take n=2 years

A=P(1+

year =4840+242

=5082

Compound interest =5082−4000

CI=1082.
