Question

after 23 years Monu will be 4 times as old as he was 4 years ago .
find his present age

Answer 1

let monu's age now be x
so,his age before 4 years was x-4
After 23 years his will be x+23
A. T. Q, x+23=4(x-4)
=>x+23=4x-16
=>x-4x=-23-16
=>-3x=-39
=>x=-39/-3
therefore, x=13
so, Monu's age now is 13 years

Answer 2

X+23=4 (x-4) Then x=13
