Question 60

The following bar chart shows the revenue (in thousand rupees) generated from the sale of 5 different objects, Q1 to Q5.

The following bar chart shows the profit percentage gained through the sales of these 5 objects.

Profit percentage$$ =\frac{Revenue - Cost}{Cost} \times 100$$

What is the cost incurred in the procurement and sale of Q1?

Solution

For object Q1 ::

Profit percentage$$ =\frac{Revenue - Cost}{Cost} \times 100$$

$$20=\frac{180000 - Cost}{Cost}\times\ 100$$

$$1=\frac{180000 - Cost}{Cost}\times\ 5$$

$$5\times(180000 - Cost) = Cost$$

$$900000 - 5\times Cost = Cost$$

$$6\times Cost = 900000$$

Cost = 150000
