Question

a merchant gained 30% on 1/4 of his capital, lost 20%on2/3 of his capital and made no gain no loss on the remainder. the gain/loss on the whole is​

Answer 1

Answer:

initial capital = 120Rs.

+Gains = 9Rs.

-loss = 16Rs.

net amount = 120+9–16= 113Rs.

Since the net amount(113) is less than the actual capital (120), it is concluded that he has suffered a loss of 7Rs.

Since in your question the amount is not given, we can generalise the loss by deriving the % of loss using that example.

Loss = 7Rs.

Capital = 120Rs.

Loss% = 7/120*100 = 5.83% or you can say he suffered a loss of 7/120th on the whole.
