Question

A natural number has been dicided into two parts inthe ratio 7:11 . If the differences of two parts is 20 , find the number and the two parts​

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

Hence, this is the answer.
