Read Solution (Total 11)
-
- if ankit age=x
nikita age=240/x
then (2*(240/x))-x=4 so,x=20
ankit age=20yrs
nikita age=(240/20)=12yrs - 12 years agoHelpfull: Yes(25) No(3)
- Ankita=x, nikita=y;
two equations are xy=240
2y=x+4
x=20,y=12
ans is 12
- 12 years agoHelpfull: Yes(11) No(1)
- let the age of nikita is x
xy=240
2x-y=4
2x-240/x=4
x=12(ans) - 12 years agoHelpfull: Yes(6) No(2)
- if ankit age=x
nikita age=240/x
then (2*(240/x))-x=4 so,x=20
ankit age=20yrs
nikita age=(240/20)=12yrs - 12 years agoHelpfull: Yes(5) No(2)
- 12
xy=240
2x-y=4
solving these x=12
- 12 years agoHelpfull: Yes(2) No(1)
- let ankit's age be X years then Nikita age=240/X years
Therefore 2*(240/X)-4 480-X^2=4X x^2+4X-480=0
(X+24)(X-20)=0 X=20
Hence Nikita's age= (240/20)years=12years - 11 years agoHelpfull: Yes(2) No(0)
- ankit's age=20 yrs
nikita's age=12 yrs
let ankit's age be a yrs
and nikita's age will be n yrs
so the reqd eqn is
a^2+4a-480=0 - 11 years agoHelpfull: Yes(2) No(0)
- nikita age is 12...na=240...and 2n=a+4....solving these we get n=12...
- 12 years agoHelpfull: Yes(1) No(0)
- a*n = 240
2n-4 = a
n^2-2n-120=0
n=12
nikita = n
ankit = a
age of nikita = 12 yrs - 11 years agoHelpfull: Yes(1) No(0)
- a.n=240
and 2n-a=4
so a=2n-4
put it in 1st eqn n=12 so a=20 - 11 years agoHelpfull: Yes(1) No(0)
- ans is 12
- 11 years agoHelpfull: Yes(1) No(1)
