Answer:
mark me as brainiest or thank me plz
Step-by-step explanation:
Let the present ages of son and father be x and (60 -x) years respectively.
Then, (60 - x) - 6 = 5(x - 6)
54 - x = 5x - 30
6x = 84
x = 14.
Son's age after 6 years = (x+ 6) = 20 years..
Answer:
The answer is 20 yrs.
Pls mark my answer as brainliest!!!
Step-by-step explanation:
Let the present age of son and his father be x and y yrs respectively
According to first condition- x+y=60......(1)
Son's age 6 yrs ago=x-6
Father's age 6 yrs ago= y-6
According to second condition - (y-6)=5(x-6)
=y-6=5x-30
=5x-y+6-30=0
=5x-y-24=0
=5x-y=24...(2)
By adding eqn 1 &2, we get x=14
By substituting x=14 in eqn 1 we get y=46
The present ages of son and his father is 14 &46 respectively.
Son's age 6 yrs from now=14+6=20 yrs.
