400 apples were bought at ₹1220 per hundred and were sold at a profit of ₹920. Find the selling price (in ₹) per dozen of apples.

Solution / समाधान

Cost price of 100 apples = ₹1220

So, cost price of 400 apples:

$= 1220 \times 4$

$= 4880$

Profit = ₹920

Therefore, total selling price:

$= 4880 + 920$

$= 5800$

Selling price of 1 apple:

$= \frac{5800}{400}$

$= 14.5$

Selling price of 12 apples (1 dozen):

$= 14.5 \times 12$

$= 174$

Correct Answer / सही उत्तर:

👉 174
