Question

The sum of two whole numbers is 88. The ratio of the two number is 7:4, what are the two numbers?​

Answer 1

Answer:

Correct option is

C

36,84

Let the 2 numbers be x and y

y

x

=

3

7

x−y=48

3x=7y

x=

3

7y

=

3

7y

−y=48

=

3

4y

=48

y=

4

48×3

=36

x=y+48=36+48=84

Answer 2

Answer:

We have,

Let the two whole number is x and y.

Then,

x−y=66...(1)

Now, Acoording to question,

yx=25

⇒2x=5y

⇒x=25y

Put in equation (1) and we get,

x−y=66

⇒25y−y=66

⇒5y−2y=66×2

⇒3y=66×2

⇒y=366×2

⇒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 110 and 44
