Question

Oranges are bought at 5 for Rs. 10 and sold at 6 for Rs. 15. His gain per cent is

(a) 50 %

(b) 40 %

(c) 35 %

(d) 25 %

Answer 1

Answer : (d)

CP of 5 oranges = Rs . 10

SP of 6 oranges = Rs. 15

Now CP of 1 orange $=Rs.\frac{10}{5}=Rs.2$

and SP of 1 orange = Rs. $\frac{15}{6}=Rs.\frac{5}{2}$

Gain $=SP-CP=Rs.\frac{5}{2}-\frac{2}{1}=Rs.\frac{1}{2}$

$Gain\%=\frac{Totalgain\times 100}{CP}$

$=\frac{\frac{1}{2}\times 100}{2}=\frac{1\times 100}{2\times 2}=25\%$
