Question

A vendor bought bananas at 6 for Rs. 10 and sold them at 4 for Rs.6. Find his gain or loss percent?

Answer 1

CP of 6 banana = Rs. 10
CP of 1 banana $=\frac{10}{6}=1.667$
SP of 4 banana = Rs. 6
SP of 1 banana $=\frac{6}{4}=\frac{3}{2}=1.5$
CP > SP, So loss

Loss = CP - SP $=1.667-1.5=0.167$

$Loss\%=\frac{Loss}{C.P}\times 100\%$

$=\frac{0.167}{1.667}\times 100$

$=10\%$
