Question

If a quarter kilogram costs rs 60 then how much will cost for 150 grams

Answer 1

R s. 36

Explanation:

1kg ⇒ 1000g

So, a quarter kilogram means,

`(1)/(4)` × 1kg = 1000g ×
`(1)/(4)`

`(1)/(4)` × 1kg = 250g

According to the question,

250g = R s. 60

So, now they're asking for the price of 150g.

Let that price be x.

250g ⇒ R s. 60

150g ⇒ x

Use cross multiplication to find the value of x.

250x = 60 × 150

250x = 9000

Divide both sides by 250.

x = R s. 36
