Question

The difference of two whole numbers is 66. The ratio of two numbers is 2:5 . The linear equation formed will be :

Answer 1

Answer:

We have,

Let the two whole number is x and y.

Then,

x−y=66......(1)

Now, Acoording to question,

y

x

=

2

5

⇒2x=5y

⇒x=

2

5

y

Put in equation (1) and we get,

x−y=66

⇒

2

5

y−y=66

⇒5y−2y=66×2

⇒3y=66×2

⇒y=

3

66×2

⇒y=22×2

⇒y=44

Put the value of y in equation (1) and we get,

x−y=66

⇒x−44=66

⇒x=66+44

⇒x=110

Then, the number is 110and44

Hence, this is the answer.

Answer 2

Answer:

let, the first number be 5x

second number be 2x

according to question

Step-by-step explanation:

5x-2x= 66

3x =66

x =66/3

x =22

so, the first number is 110

second number is 44
