Question

If the cost of 7 m cloth is ₹ 700. The cost of 21 m of cloth is ₹ 2100.

• A. Rs 2142
• B. Rs 5432

Answer 1

The correct option is A

Rs 2142

Given the cost of 7 m cloth = ₹ 700

Now the cost of 1 m cloth = ₹ $\frac{700}{7}$

= ₹ 100
Cost of 21 m cloth would be 21 times of 1 m cloth.

$\Rightarrow 21\times 100$

​​​​​​​= 2100
