Given that:

Mukesh breakfast cost Rs 30 per day at a restaurant.

He deposits an amount of Rs 210 in that restaurant.

To Find:

How much days can he have his breakfast there?

We have:

1 day breakfast cost Rs 30.

Let us assume:

x days breakfast cost Rs 210.

Finding the value of x:

According to the question.

⟶ 1 : 30 = x : 210

⟶ 1/30 = x/210

Cross multiplication.

⟶ 1(210) = x(30)

⟶ 210 = 30x

⟶ x = 210/30

⟶ x = 7

∴ The value of x = 7

Hence,

He have his breakfast there for 7 days
