Question

In a sale, 3 t-shirts cost ₹450 and 2 jeans cost ₹1400, calculate the ratio of total costs of 4 t-shirts and 4 jeans.

• A. ₹ 600
• B. ₹ 2800
• C. ₹ 3400
• D. ₹ 4200

Answer 1

The correct option is C ₹ 3400

Let's find out cost of 1 t-shirt and 1 jeans.
cost of 1 t-shirt = $\frac{450}{3}$ = ₹150
$\therefore$ cost of 4 t-shirt = 150 $\times$4 = ₹600

cost of 1 jeans = $\frac{1400}{2}$ = ₹700
$\therefore$ cost of 4 jeans = 700 $\times$4 = ₹2800

Ratio of total cost of 4 t-shirt and 4 jeans = 600 : 2800
= 3 : 14
