Question

A man buys two cows for Rs. 1350 and sells one, so as to lose 6%, and the other so as to gain 7.5% and on the whole, he neither gains nor loses. What does each cow cost?

• A. 750,500
• B. 750,600
• C. 600,500
• D. 700,650
• E. None of the above

Answer 1

The correct option is B 750,600


Thus, we see that the ratio of the cost of two cows is 5 : 4.
$\therefore$ Cost of 1st cow $=\frac{1350}{5+4}\times 5$ =Rs 750
and, cost of 2nd cow =$\frac{1350}{5+4}\times 4=Rs600$
