The cost of 5 meters of a particular quality of cloth is Rs. 210. Find the cost of (i) 2 (ii) 4 (iii) 10 (iv) 13 meters of cloth of the same quality.

Given: Cost of 5 m of cloth = Rs. 210

To Find: Cost of 2m, 4m, 10m and 13m of cloth.

Formula:

(i) Substituting x₁ = 5, y₁ = 210 and x₂ = 2 in the formula,

Gives y₂ = 84

∴The cost of 2m cloth is Rs. 84

(ii) Substituting x₁ = 5, y₁ = 210 and x₂ = 4 in the formula,

Gives y₂ = 168

∴The cost of 4m cloth is Rs. 168

(iii) Substituting x₁ = 5, y₁ = 210 and x₂ = 10 in the formula,

Gives y₂ = 420

∴The cost of 10m cloth is Rs. 420

(iv) Substituting x₁ = 5, y₁ = 210 and x₂ = 13 in the formula,

Gives y₂ = 546

∴The cost of 2m cloth is Rs. 546
