Question

If SP of 6 pens is equal to the CP of 7 pens. Then find gain % (or) loss%.

• A. $12\frac{1}{2}$% gain
• B. $16\frac{2}{3}$ % gain
• C. $16\frac{2}{3}$ % loss
• D. $12\frac{1}{2}$ % loss

Answer 1

Answer: (B)

$16\frac{2}{3}$ % gain

It is given that the SP of 6 pens is equal to the CP of 7 pens.

Therefore, we would be in the profit of 1 pen.

Therefore, $Gain\%=$ $\frac{7-6}{6}\times 100$

$=\frac{1}{6}\times 100=16\frac{2}{3}$ %

$\therefore$ there is gain of $16\frac{2}{3}\%$
