Question 124

The table shows the cost of sunscreen of two brands with and without sales tax. Which brand has a greater sales tax rate? Give the sales tax rate of each brand ?$\begin{array}{ccc}\text{Quantity}& \text{Cost(in Rs.)}& \text{Cost+Tax(in Rs)}\\ X\left(100g\right)& 70& 75\\ Y\left(100g\right)& 62& 65\end{array}$

Answer 1

Brand X sunscreen cost = Rs. 70
With sales tax = Rs. 75
Sales tax paid = Rs. 75 - Rs. 70 = Rs. 5
Brand Y sunscreen cost = Rs. 62
With sales tax = Rs. 65
Sales tax = Rs. 65 - Rs. 62 = Rs. 3
Hence, tax for brand $X=\frac{5}{70}\times 100=\frac{50}{7}=7.14\%$
Sales tax for brand $Y=\frac{3}{62}\times 100=\frac{300}{62}=4.838\approx 4.84\%$
