-
- anita's age=x,sunita's age=y
x+y=43
6x-7y=11
solving the above equations:
y=19
Ans. D - 11 years agoHelpfull: Yes(11) No(2)
- let anita's age=x,sunita's age=y
before 11 years,x+y=43
after 11 years (x+11)=7(y+11)/6
6x-7y=10
on solving above two equations:y=19 - 11 years agoHelpfull: Yes(5) No(2)
- let sunita age = x
then,anita age = 43-x
so,according to question
11 + (43-x)= 7/6*(x+11),on solving this equation.
we get, x= 19
therefore sunita age=19 year. - 11 years agoHelpfull: Yes(1) No(0)
- 19
assume x+y=43
7/6y+y=43
13y=43*6
y=19 - 10 years agoHelpfull: Yes(0) No(1)
