4x×1x=196
so
4x=196
x=196/4
x=49 therefore after five years their age will be
4×49+5and 1×49+5 therefore
201:54
67:18
so
4x=196
x=196/4
x=49 therefore after five years their age will be
4×49+5and 1×49+5 therefore
201:54
67:18
expertgenius1:
sorry i made a mistake
but its not the right answer
ok..thn rewrite it pls.
yes
4x×x=196 so 4x^2=196 and then x^2=196/4 =√49= 7 so 4×7+5 : 7+5
Seems like there is a mistake.
The answer is incorrect bro.

let x be the son's age
from first condition
man's age = 4 * x
from second condition
(4*x) * x = 196
4x² = 196
x² = 49
x = 7
therefore current age of the son is 7 years and current age of man is (7*4) 28
after 5 years
son's age = 7 + 5 = 12 yrs
man's age = 28 + 5 = 33 yrs
ratio of man's age to son's after 5 years will be (33/12) 11/4
hope it answers your query
