Question

Cost of 6 kg of rice is ₹36.60: What quantity of rice can be purchased in ₹61 ?

Answer 1

We recall the definition of direct proportion

Direct proportion is the relation between two quantities whose ratio is constant.

Given:

$6 kg$ rice is in $36.60$

Using direct proportion

Quantity of rice in $61$ is $\frac{61 . 6}{36.60}$

$=10 kg$

$10 kg$ rice can be purchased in Rs. $61$
