A person bought two horses for Rs. 3500 each. One sold at a gain 15% and other sold at a loss of 7%. Find his gain or loss on the whole.

A
8% gain
B
8% loss
C
5% loss
D
4% gain

Solution:

$\begin{array}{l} E a c h h o r s e C P = 3500 \\ 1^{S t} H o r s e S P = 3500 \times \frac{115}{100} = 4025 R u p e e s \\ 2^{n d} h o r s e a t 7 % l o s s = 3500 \times \frac{93}{100} = 3255 \\ T o t a l 2 h o r s e s S P = 4025 + 3255 = 7280 \\ a c t u a l \cos t o f 2 h o r s e s = 3500 + 3500 = 7000 \\ p r o f i t % = \frac{p r o f i t}{C P} \times 100 \\ = \frac{280}{7000} \times 100 % = 4 % \end{array}$
