Answer 2

Answer:

The number is 28.125.

Step-by-step explanation:

Sum of the numbers = 90

Let the second number be = x

First number = x/4

Value of x = 112.5

x/4 + x = 90

⇒ x/4 + 4x/4 = 90 (L.C.M.)

⇒ 5x/4 = 90

⇒ x = (90 × 5)/4 (Cross multiplication)

⇒ x = 22.5 × 5 = 112.5

Since, the number is 1/4 of x, the number = 112.5/4 = 28.125

∴ The number is 28.125
