Question

If the cost of 7 m long cloth is ₹294, then find the cost of 5 m long cloth.

Answer 1

Cost of 7 m long cloth = ₹294

Applying unitary method, where firstly we find the value of one unit and then the value of required number of units.

Cost of 1 m cloth = $\frac{294}{7}$ = ₹42

Cost of 5 m cloth = 42 $\times$ 5 = ₹210

Thus, the cost of 5 m long cloth is ₹210.
