Read Solution (Total 10)
-
- let the sunil age =x
father's age=78-x
after 6 years sunil's age=x+6;
after 6 yeares father's age=84-x;
after 6 years fathers age is equal to the twice of sunil-s age
so,
84-x=2(x+6)
3x=72
x=24;
present age of sunil=24years;
present age of sunil's father=78-24=54 - 8 years agoHelpfull: Yes(6) No(0)
- 24 & 54 years
If presents ages(in years) of Sunil=S & Father=F, then
S+F=78 ---(i) &
2(S+6)=F+6 or 2S-F= -6 ---(ii)
From (i) & (ii), S=24, F=54 - 8 years agoHelpfull: Yes(5) No(1)
- by solving the above equations ,ans is-son=28 & father=50
- 8 years agoHelpfull: Yes(0) No(3)
- age of son=24
age of father= 54.
x+y=78
2(x+6)=y+6
solve for x and y - 8 years agoHelpfull: Yes(0) No(0)
- let age of sunil=x
sunil+ father=78
after 6 yrs sunil+father=78+12 bcs 6 yrs incrs of sunil and also his father
now father age wll be twice =2x
x+2x=78+12
3x=90
x=30
now present age of sunil=x-6=30-6=24
father =2x=2*30=60-6=54 - 8 years agoHelpfull: Yes(0) No(2)
- Sunil's age + Father's age = 78 -----------(i)
after 6 years
Father's age + 6 = 2(Sunil's age + 6)
from eq. (i)
78 - Sunil's age = 2(Sunil's age) + 12
3(Sunil's age) = 72
Sunil's age = 24 ANS
So from eq. (i)
father's age = 78 - 24
= 54 ANS. - 8 years agoHelpfull: Yes(0) No(0)
- sum of ages of Sunil and Father x+y=78
6 yrs hence 6+y=2x
x=28
y=50 - 8 years agoHelpfull: Yes(0) No(2)
- let ages of sunil and father be x and 78-x
x+y=78
6 years hence 84-x=2(x+6)
3x=72
x=24
y=54 - 8 years agoHelpfull: Yes(0) No(0)
- Let, Sunil = S & Father = F
.`. (s+6) + 2(s+6) = 78 + 6 + 6
=> S = 24
So, F = 78 - 24
= 54 - 8 years agoHelpfull: Yes(0) No(0)
- age of sunil and father=x-78
2(x-6)
78+6=84
84-x=2x-12
3x=72
x=24
so sunil age is 24-78=54
- 8 years agoHelpfull: Yes(0) No(0)
