Answer:
(3) 16,24
Step-by-step explanation:
Let first number = X
and second number = y
so according to question
(x+y = 40) ........ (i)
and (x-y = 8) .....(ii)
from (ii) X = y+8 ....(iii)
replace the value of X in (i)
= y+8+y = 40
= 2y = 40-8
= y = 32/2
= y= 16 answer
replace the value of y in (iii)
= X = 16+8
= X = 24 answer
so, x=24 and y=16
