• B. $191;19\frac{1}{5}$%
• C. $135;33\frac{1}{3}$%
• D. $135;43\frac{1}{3}$%

Answer 1

Answer: (C)

$135;33\frac{1}{3}$%

As per question,

Material : Labour : Overheads is $4:3:2$

Then total cost $=4+3+2=9$

If cost of labour is Rs $45$

Then, total cost $=\frac{9}{3}\times 45=135$

Profit on materiel$180-135=45$

Then, $\%$ of profit$=\frac{45}{135}\times 100=33\frac{1}{3}\%$
