Question

find the principal which amounts to rupees 17640 at the rate of 5p.c.p.a compound annually for two years?​

Answer 1

Answer:

The Principal is Rs 16000.

Given that:

Amount = Rs 17640

Rate of interest = 5% p.a.

Time = 2 years

To Find:

Principal

Formula used:

In compound interest.

A = P(1 + R/100)ᵀ

Where,

A = Amount

P = Principal

R = Rate of interest

T = Time

Finding the principal:

Substituting the given values in formula.

⟶ 17640 = P(1 + 5/100)²

⟶ 17640 = P(1 + 0.05)²

⟶ 17640 = P(1.05)²

⟶ 17640 = P × 1.05 × 1.05

⟶ 17640 = 1.1025P

⟶ P = 17640/1.1025

⟶ P = 16000

∴ Principal = Rs 16000
