Answer 1

★ Required AnswEr:

• The required smaller number = 36

★ Given Information:

• The ratio of two numbers is 5:7 and difference between them is 12.

★ Need To Find Out:

• The required smaller number = ?

★ Required Solution:

Let the required smaller number be 5y.

And, the required larger number be 7y.

★ According to the problem,

=> 5y - 7y = 12

=> 7y - 5y = 12

=> 2y = 12

=> y = 12/2

=> y = 6

★ Therefore:

• The Smaller Number = 5y
• The Smaller Number = 5 × 6
• The Smaller Number = 30

★ Hence:

• The required smaller number is 30.

Answer 2

Given:

• Ratio of two numbers is 5:7 and difference between the is 12.

To Find:

• Smaller number

Solution:

Let the smaller number be 5y,

and the larger number be 7y.

As we know,

• Difference between the ratio of two numbers is 12.

According to the question:-

→ 5y - 7y = 12

→ 7y - 5y = 12

→ 2y = 12

→ y = 12/2

→ y = 6

Therefore;

★ Finding Smaller number:-

→ 5y

→ 5 × 6

→ 30

Hence,

• Smaller number is 30.
