SSC GD 2023 PYQ — Question 48

The correct answer is Option 2 i.e. $71 \frac{3}{7} percent$.

Let CP of 1 kg sugar = Rs. 1

CP of 100 kg sugar = Rs. 100

During selling, profit = 20%

and he uses 30% less weight than the marked weight.

So, SP of 70 kg sugar = Rs 120

SP of 1 kg sugar = Rs. (120/70) = Rs. (12/7)

Profit = (SP - CP)

Profit = Rs. (12/7 - 1)

Profit = Rs. 5/7

Profit% = (Profit/CP) x 100

Profit% = 5/7 × 100 = 500/7 = $71 \frac{3}{7} percent$

The grocer has a profit of $71 \frac{3}{7}$%.
