Question

If Dipti can eat $12$ eggs in $x$ minutes, then how many eggs can she eat in $y$ hours?

• A. $\frac{720}{xy}$
• B. $\frac{xy}{720}$
• C. $\frac{720y}{x}$
• D. $\frac{720x}{y}$

Answer 1

Answer: (C)

$\frac{720y}{x}$

Given Dipti eats $12$ eggs in $x$ minutes.

$y$ hours $=$ $60\times y=60y$minutes

Then Dipti eats eggs in one minutes $=$ $\frac{12}{x}$

Then $y$ hours or $60y$ minutes =$\frac{12}{x}\times 60y=\frac{720y}{x}$
