Question 55
Study the graph and answer the question that follows:
The graph indicates the cost of the production of a firm.
A = Raw material cost
B = Packing material cost
C = Fixed manufacturing expenses
D = Labour cost
The total value in rupees of all sectors is 120.0 lakh.
If the total labour cost increases to Rs. 2.4 lakh, what percentage increase does it represent?
Solution
Percentage cost in labour cost (D) = $$(100-(49+39.5+11))\%=0.5\%$$
So, total value of labour cost = $$\dfrac{0.5}{100}\times\ 120$$ = Rs. 0.6 lakh
Now, total labour cost increases to Rs. 2.4 lakh
So, required percentage increase = $$\dfrac{2.4-0.6}{0.6}\times\ 100\ \%\ =300\ \%\ $$
