Answer 1

Answer:

• Quantity of Primer to be 90 litres.

Given:

• A mixture of 210 litres.
• Ratio of paint and primer is 3:2.
• Ratio of again paint and primer is 4:3.

To Find:

• What is the quantity of primer = ?

Solution:

According to the question,total mixture is 210 litres and the ratio of paint and primer is 3:2 and again in ratio is 4:3 and we are said to find quantity of primer.

Let's assume:

• Let the quantity of paint be 3x.
• Let the quantity of primer be 2x.

According to the question,

•3x + 2x = 210

•5x = 210

•x = 210/5

•x = 42

Quantity of Paint = 3x = 3 × 42 = 126 litres

Quantity of Primer = 2x = 2× 42 = 84 litres

Now,

The ratio is to 4:3.

Let's assume:

• Let the quantity of paint be 4x.
• Let the quantity of primer be 3x.

According to the question,

•4x + 3x = 210

•7x = 210

•x = 210/7

•x = 30

Quantity of paint = 4x = 4 × 30 = 120 litres

Quantity of primer = 3x = 3× 30 = 90 litres

Hence, quantity of primer be 90 litres.
