​What is the principal amount which earns ₹154/- as a compound interest for the second year at 10% per annum?​

Correct option is D

Given:

CI (Second year) = 154

Rate = 10%

Formula used:

The compound Interest for the second year (CI) = Principal Rate×(1+Rate)

Solution:

Let the Principal is =$$P$$​

Substitute the value in above formula:

(CI) = Principal Rate×(1+Rate)

154= $$P$$​×$$\frac{10}{100}$$×$$(1+\frac{10}{100})$$

154= $$\frac{P}{10}$$×$$\frac{11}{10}$$ 

​$$P$$= $$\frac{154×100}{11}$$ 

$$P$$= 1400

Thus the correct answer is (D)
