• A. Rs.430
• B. Rs.432
• C. Rs.442
• D. Rs.452

Answer 1

The correct option is B

Rs.432

Given that S.I. = ₹ 432, R = 6 % p.a. and T = 3 years

Let the principal be P.

Simple interest is given by,

S.I. = $\frac{PRT}{100}$

Substituting the values,

$432=\frac{P\times 6\times 3}{100}$

$P=\frac{432\times 100}{6\times 3}$

= $\frac{144\times 100}{6}$

= ₹ 2400
