Question

Raj bought 10 chocolates, each for ₹ 40. He sold 6 of them at ₹50 each, and the rest of it at ₹ 55 each. Find the percentage of profit he made.

• A. $20\%$
• B. $30\%$
• C. $25\%$
• D. $40\%$

Answer 1

The correct option is B

$30\%$

CP of one chocolate bar = ₹ 40
CP of 10 chocolate bars = ₹ 40 x 10
= ₹ 400

SP of 6 chocolate bars at ₹ 50
= 6 x ₹ 50
= ₹ 300

Remaining number of chocolate bars = 10 - 6 = 4

SP of 4 chocolate bars at ₹ 55
= 4 x ₹55
= ₹ 220

Total SP = ₹ 300 + ₹ 220 = ₹ 520

Since SP > CP, we have a profit.

Profit = SP - CP = ₹ 520 - ₹ 400 = ₹ 120

$\text{Profit}\%=\frac{\text{Profit}}{\text{CP}}\times 100$
$=\frac{₹120}{₹400}\times 100$
$=30\%$
