Question

A natural number has been divided into two parts in the ratio 7:11 if the diffrence of the parts is 20, find the number and the new part​

Answer 1

Step-by-step explanation:

Let the common multiple be x

Then,

According to given question,

11x−7x=20

⇒4x=20

⇒x=5

Therefore

The first number =7x=7×5=35

Second number is =11x=11×5=55

Then the total is 11x+7x=18x=18×5=90

Answer 2

Step-by-step explanation:

let the common multiple= X

then the numbers are 11x and 7x

according to question,

11x-7x= 20

4x=20

x=20/4

x=5

therefore the numbers are,

11x = 11*5= 55

and, 7x =7*5= 35
