Answer 1

Given:-

• A business man purchase 75 m clothes at a rate of Rs. 18 m. To gain Rs. 90 the selling price of 1 m cloth is .

To Find:-

• The selling price price of 1 m cloth = ?

Solution:-

• To calculate the selling price price of 1 m of clothes at first we have to find cost price of clothes then with the help of cost price we will find out selling price of clothes.

⟼ The cost price of clothes = Rate × length of clothes

⟼ The cost price of clothes = 18 × 75

⟼ The cost price of clothes = Rs. 1350

• Now calculate selling price of clothes:-

⟼ The selling price of clothes = Cost price + gain

⟼ The selling price of clothes = 1350 + 90

⟼ The selling price of clothes = Rs. 1440

• Now calculate selling price of 1 m of cloth:-

⟼ Selling price of 1 m of cloth = selling ÷ length of clothes

⟼ Selling price of 1 m of cloth = 1440 ÷ 75

⟼ Selling price of 1 m of cloth = Rs. 19.20

Hence,

• The selling price of 1 m of cloth = Rs. 19.20
