Answer 1

Explanation:

(a) Here, Principal (P) = Rs. 1,200, Rate (R) = 12% p.a., Time (T) = 3 years

Simple Interest = \frac{P\times R\times T}{100}=\frac{1200\times12\times3}{100}=Rs.\ 432

100

P×R×T

=

100

1200×12×3

=Rs. 432

Now, Amount = Principal + Simple Interest

= 1200 + 432

= Rs. 1,632

(b) Here, Principal (P) = Rs. 7,500, Rate (R) = 5% p.a., Time (T) = 3 years

Simple Interest = \frac{P\times R\times T}{100}=\frac{7500\times5\times3}{100}

100

P×R×T

=

100

7500×5×3

= Rs. 1125

Now, Amount = Principal + Simple Interest

= 7,500 + 1,125

= Rs. 8,625
