Answer 1

Answer:

numbers are 120 and 100.

Step-by-step explanation:

Let no. be x and y.

:- x + y = 220

x - y = 20

ATQ-

(x + y) + ( x - y ) = 240

2x = 240

x = 240 ÷ 2

x = 120

Therefore,

y = 220 - 120

y = 100

Hence, The three digit numbers are= 120 and 100

Answer 2

Answer:

let no be x and y

x + y = 20

x - y = 20

A /Q ( x+ y) + ( x - y) = 220

2 x = 240

x = 240 *2

x = 120

Therefore y = 220 - 120

= 100

The numbers are........ = 120 and 100......
