(b)$3 \frac{6}{7} \%$ gain
(c)$3 \frac{2}{7} \%$ loss
(d)$2 \frac{6}{7} \%$ gain
Answer
Answer (as printed): D
Explanation
Suppose he buys 6 eggs of each kind. C.P. of 12 eggs $=₹\left(\frac{1}{2} \times 6+\frac{2}{3} \times 6\right)=₹7$. S.P. of 12 eggs $=₹\left(\frac{3}{5} \times 12\right)=₹7.20$. $\therefore$ Gain $=\left(\frac{0.20}{7} \times 100\right)\%=2\frac{6}{7}\%$.
