Question

Gopi borrowed Rs. 1800 at 12% per annum for 2 years and Krishna borrowed Rs. 1200 at 18% per annum for 3 years. Then the ratio of interests paid by them is

• A. 1 : 2
• B. 2 : 3
• C. 3 : 1
• D. 2 : 1

Answer 1

The correct option is B 2 : 3

Gopi :
P = Rs. 1800
R = 12 %
T = 2 years
$I_1=\frac{PTR}{100}$

$\frac{1800\times 2\times 12}{100}$
Rs. 432
Krishna :
P = Rs. 1200
R = 18 %
T = 3 years
$I_2=\frac{PTR}{100}$

$=\frac{1200\times 3\times 18}{100}$
Rs. 648
$I_1:I_2=432:648$
= 2 : 3
