Question

If $Rs.8400$ is divided among A, B and C in the ratio $\frac{1}{5}:\frac{1}{6}:\frac{1}{10}$, what is the share of A?

• A. $Rs.1800$
• B. $Rs.3000$
• C. $Rs.3600$
• D. $Rs.4000$

Answer 1

Answer: (C)

$Rs.3600$

$A:B:C=(\frac{1}{5}:\frac{1}{6}:\frac{1}{10})\times 30[30$ is LCM of $5,6$ and $10]$
$A:B:C=6:5:3$
Share of $A=\frac{5}{6+5+3}\times 8400$
$=\frac{6}{14}\times 8400$
$=6\times 600=Rs.3,600$
