Question

By selling tea for $Rs67.20$ per kg, a profit of $12\%$ is made, find profit made by selling $8$ kg tea.

• A. $Rs$ $57.60$
• B. $Rs$ $67.60$
  
• C. $Rs$ $52.60$
  
• D. none of these

Answer 1

The correct option is A $Rs$ $57.60$

Given, Profit % by selling 1 kg of tea $=\frac{S.P-C.P.}{C.P.}\times 100=12$ %
$⟹\frac{67.20-C.P.}{C.P.}\times 100=12$
$⟹67.20-C.P.=0.12C.P.$
$⟹1.12C.P.=67.20$
$C.P.=Rs60$
So, C.P. of $8$ kg tea $=Rs8\times 60=Rs480$
S.P. of $8$ kg tea $=Rs8\times 67.20=Rs537.6$
$⟹Profit=SP-CP=Rs537.6-Rs480=Rs57.60$
