Question

The sum of two number is 30.the larger number is 5 more than 4 times the smaller one. find the number

Answer 1

Let us assume, x and y are the two numbers and x > y

Given:

x + y = 30 -----------1

Also given:

x = 4y + 5 ---------2

Substitute the value of x from equation 2 in equation 1

4y + 5 + y = 30

5y = 25

y = 5

Therefore, x = (4 * 5) + 5 = 25

The Two numbers are 25 and 5.

Answer 2

Given :

• Sum of two number is 30.
• Larger number is 5 more than 4 times the smaller one.

To find :

• The number

According to the question,

Let the first number be x

So,the equation formed is x + 4x + 5

→ x + 4x + 5 = 30

→ 5x = 30 - 5

→ 5x = 25

→ x = 25 ÷ 5

.°. x = 5

So,the smaller number is 5

Larger number is 4x + 5 = 4 × 5 + 5 = 25...
