Answer 1

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.

Answer 2

Question:-

• Mukesh break fast cost rs 30 per day at a restaurant.if he deposits an amount of rs 210 inThat restaurant ,how much days can he have his breakfast there.

To Find:-

• How much days can he have his breakfast there.

Solution:-

• Let x days be breakfast cost ₹ 210

Now ,

We have to find the number of days:-

$\dashrightarrow\sf \: 1 : 30 = x : 210$

$\dashrightarrow\sf \: \dfrac { 1 } { 30 } = \dfrac { x } { 210 }$

$\dashrightarrow\sf \: 30x = 210$

$\dashrightarrow\sf \: x = \cancel\dfrac { 210 } { 30 }$

$\dashrightarrow\sf \: x = \cancel\dfrac { 21 } { 3 }$

$\dashrightarrow\sf \: x = 7$

Hence ,

• The have his breakfast for 7 days.
