In some quantity of ghee , 60 percent is pure ghee and 40 percent is vanaspati . If 10 kg of pure ghee added , then the strength of vanaspati ghee becomes 20 percent . The original quantity was

A. 40 kg

B. 50 kg

C. 10 kg

D. 20 kg

Answer: Option C

Solution(By Examveda Team)

Let initial quantity of ghee be 100x
it contain 60xpure ghee
and 40x vanaspati
after adding 10 kg pure ghee
total weight = (100x + 10) kg
it contains (60x + 10) kg pure ghee
and 40x vanaspati
% of vanaspati = 40x/(100x + 10) = 20/100
40x/(100x + 10) = 1/5
5 × 40x = (100x + 10)
200x = 100x + 10
100x = 10 which is initial weight of ghee.
