Question

Find two numbers such that one is five times the other and their difference is 20​

Answer 1

Let one no be x and other be y.

Where x > y.

Now,

x = 5y

x - 5y = 0 ___(1)

x - y = 20 ___(2)

➡️Subtract (1) from (2) :

x - y - x + 5y = 20 - 0

4y = 20

✔️y = 5.

x = 5y

✔️x = 25.

➡️ The nos are 25 and 5.
