(E) None of these​

Answer 1

Step-by-step explanation:

let x be the first number

then second number will be=56-x

given: x+4 =(56-x)

: 2x=52

:x=26 is the first number

and x+4=30 is the second number

B) 26&30

Answer 2

Answer:

ans. Option (B).

Step-by-step explanation:

Let one no. be = x

& other be = y.

Acc. to condition,

x+y = 56 --------(1)

y-x = 4 ---------(2) [assuming that (y>x)]

Subtract (2) from (1), that is [(1) - (2)]

we get,

[x+y] - [y-x] = 56 - 4

=> x+y-y+x = 52

=> 2x = 52

or x = 52/2 = 26.

Put the value of x into (1),

we get,

26+y = 56

or y = 56-26 = 30.
