Question

A man sold $10$ eggs for $5$ rupees and gained $20\%$. How many eggs did he buy for $5$ rupees?

• A. $12$
• B. $14$
• C. $25$
• D. $16$

Answer 1

The correct option is A $12$

Given that

Selling price $=SP=5$ rupees

cost price $=CP$

Gain $\%=\frac{SP-CP}{CP}\times 100\%$

given that

Gain $\%=20\%=\frac{5-CP}{CP}\times 100\%$

$CP=25-5CP$

$CP=\frac{25}{6}$ rupees

10 eggs cost $\frac{25}{6}$ rupees

cost of 1 egg $=\frac{25}{60}$

Total eggs for 5 Rupees $=\frac{5}{\frac{25}{60}}$$=12$ Eggs
