Question

A man sells 2 cows for Rs. 4,000 each, neither gaining nor losing in the deal. If he sold one cow at a gain of 25%, then the other cow is sold at a loss of :

• A. 16.66%
• B. 18.22%
• C. 25%
• D. 30%

Answer 1

The correct option is A 16.66%

Given
Total C.P = Total S.P
Total S.P = Total C.P
C.P of the first cow$=\frac{100\times S.P}{100+profit}=\frac{100\times 4000}{100+25}=3200$
C.P of other cow = total C.P - C.P of first cow $=8000-3200=4800$
Loss = C.P-S.P $=4800-4000=800$
Loss %$=\frac{800}{4800}\times 100=16.66$ %
