Answer: (c)

Let the cost price = Rs. x

Profit = Rs. x

Cost price of 8 dozen pencil = Rs. 7x

Gain per cent = $x/{7x} × 100 = 100/7 = 14{2}/7$ %

Answer: (b)

Given SP of 12 marbles = Rs. 1, loss = 20%

∴ CP of 12 marbles = Rs. $1/0.8$ = Rs. 1.25

Now, SP of 12 marbles at a gain of 20%

= CP × 1.2 = 1.25 × 1.2 = Rs. 1.5

This implies that in order to gain 20%, he should sell 12 marbles for Rs. 1.5.

For Rs. 1, he should sell $12/1.5$ = 8 marbles.
