Question

The cost of making an article is divided between materials, labour and overheads in the ratio $5:3:1$. The cost of the materials is $Rs.125$, what is the cost of labour?

Answer 1

Let the total cost of making an article be $x$ Rs.

The cost is divided between materials, labour and overheads in the ratio $5:3:1$

Let $x$ be the cost of overheads, then cost of labour is $3x$ and cost of materials is $5x$.

Since, the cost of materials is $125$ Rs.

$⟹5x=125$

$\therefore x=25$

Thus, the cost of labour $=3x=3\times 25=75$

Hence, the cost of labour is $75$ Rs.
