Solution

Answer : (a)

Let CP of an article = Rs. 100

$∴ S P = \frac{6}{5} o f C P = \frac{6}{5} \times 100 = R s . 120 G a i n = S P - C P = R s . 120 - R s . 100 = R s . 20$

$G a i n % = \frac{T o t a l g a i n \times 100}{C P} = \frac{20 \times 100}{100} = 20 %$

The selling price of an article is $\frac{6}{5}$ of the cost price. The gain per cen is

(a) 20 %

(b) 25 %

(c) 30 %

(d) 120 %

Answer : (a)

Let CP of an article = Rs. 100

$∴ S P = \frac{6}{5} o f C P = \frac{6}{5} \times 100 = R s . 120 G a i n = S P - C P = R s . 120 - R s . 100 = R s . 20$

$G a i n % = \frac{T o t a l g a i n \times 100}{C P} = \frac{20 \times 100}{100} = 20 %$
