Question

The ratio of two number is 7:4 and their difference is 15.find the two numbers?​

Answer 1

5 is the answer of this question

Explanation:

7x-15=4x

7x-4x=15

3x=15

X=15/3

X=5

Answer 2

Given :-

• The ratio of two number is = 7:4

• Their difference is = 15

To Find :-

• What are the two numbers?

Solution :-

Given that,

The ratio of two number is 7:4.

Let the first and second number be 7x and 4x respectively.

Again,

Their difference is 15.

Therefore,

7x -4x = 15

⟼ 3x = 15

$⟼x = 5$

Therefore,

first number is = 7x = 35

Second number is = 4x = 20

______________________________________

Verification :-

Given that,

The ratio of two number is 7:4.

Hence,

Ratio of two numbers = 7:4

⟼ 35:20 = 7:4

⟼ 7:4 = 7:4

R.H.S = L.H.S

Again,

Their difference is 15

⟼35 - 20

= 15

L.H.S = R.H.S

Hence, verified
