Q. Oranges are bought at 7 for rupees 3. At what rate per hundred must they be sold to gain 33%?

(A) Rs 56
(B) Rs 60
(C) Rs 58
(D) Rs 57

Correct Answer - Option(D)

Explanation by: Punit Bajpai

7 orange ka price-3rs,
1 orange ka price -3/7,
100 orange ka price-(3/7)×100,
                                   =300/7,
33 %of 100 orange price=(300×33)÷(7×100)=99/7,
Now the price after 33 % benefit=(300+99)÷7=57
Answer is D
