Question

one number is four less than three times another if their sum is increased by five, the result is 25 find the number

Answer 1

let first no. is = x
second no. is = y
so A.T.Q.
x+4=3y
so y=(x+4)÷3
x+y+5=25
x+y=20
so x+(x+4)÷3=20
3x+x+4=60
4x+4=60
x+1=15
so x=14
now y=(x+4)÷3
so y=18÷3=6
so first no.=14
second no.=3

Answer 2

let   one number be x and the other number be y.

from the first statement

x-4 = 3y.....................................................(1)

from the second statement we get

x+y+5=25..................................................(2)

x+y=20

x=20-y........................................................(3)

sub (3) in (1) we get

20-y-4 = 3y

16= 4y

y=4............................................(4)

sub y=4 in (3) we get

x=20 - 4

x = 16

x=16,y=4
