विकल्प

• (12, 72)

• (13, 78)

• (18, 108)

• (10, 100)

Answer 1

One number is 6 times the other. If their difference is 90, the numbers are (18, 108).

Explanation:

Let the smaller number be x,

Then the larger number is 6x, since one number is 6 times the other,

Given:

6x − x = 90

5x = 90

x = `90/5`

∴ x = 18

So the numbers are:

Smaller: x = 18

Larger: 6x = 6(18) = 108

Therefore, the numbers are 18 and 108.
