Question

• The difference of two numbers is 9 and the numbers are in the ratio 4:7. Find the numbers.

Given

• Difference of 2 numbers = 9
• Ratio of these 2 numbers = 4:7

To find

• The 2 numbers

Solution

• Let the 2 required numbers be x and y, and in the question they gave us the ratio 4:7, then according to the question.

→ 7x - 4x= 9

→ 3x = 9

→ x = 9/3

→ x = 3

∴ The value of x is 3

→ 4x = 4(3) = 12

→ 7x = 7(3) = 21

∴ The 2 numbers are 12 and 21

Verification

• 7x - 4x = 9
• 21 - 12 = 9
• 9 = 9
• L.H.S = R.H.S
