Question 62

The following table shows the number of chairs made of plastic and of steel in 5 different colours that were sold from a furniture showroom during a sale.

The total number of chairs of colour C3 sold are what percentage of all the chairs of these 5 colours sold, both plastic and steel ones put together? [ Give your answer correct to 2 decimal places.]

Solution

The total number of chairs of colour C3 sold = 8+14 = 22

All the chairs of these 5 colours sold, both plastic and steel ones put together = 10+12+12+6+8+14+6+18+9+11

= 106

Percentage = $$\frac{22}{106}\times100$$

= $$\frac{2200}{106}$$

= 20.75%
