Question

plz help me...​

Answer 1

The parts of the sum are 55 and 80.

Explanation:

Let,

'x' be the smaller part and

'y' be the greater part of the number.

The sum is x+y = 135. --------(1)

The greater part y = x+25. ---------(2)

Substitute (2) in (1),

⇒ x+(x+25) = 135

⇒ 2x+25 = 135

⇒ 2x = 110

⇒ x= 110/2

x = 55

The smaller part is 55.

Substitute x=55 in (2)

y = 55+25 = 80

The greater part is 80.
