Answer 2

Answer:

➜Given:

• A man buys eggs at Rs 9.60 per dozen
• sells 20 eggs for Rs 18.

➜To Find:

his gain or loss per cent?

➜Formula used:

• Gain % = (Gain / CP) * 100
• Loss % = (Loss / CP) * 100

➜Solution:

A dozen is 12. A score is 20.

One egg bought at Rs 9.60 per dozen is thus Rs 0.80 (9.60 divided by 12)

One egg sold at Rs 18 per dozen is Rs 0.9. (18 divided by twenty)

Profit is thus Rs 0.10 per egg. His gain over the purchase price is 1/8th (or 12.5%)
