- Let before 50 year grandmother's age 2x then mohan's age was x
So now (2x+50)-(x+50)=6
X=6 year
So present age of mohan=6+50=56 year

- ans: consider mohan's age =x and grandmother's age=y
y-x=6 .....(1)
(y-50)=2(x-50) ......(2)
by solving this equation x=56 - 10 years agoHelpfull: Yes(8) No(0)
- g-m=6----(1)
g-50=2*(m-50)
2m-g=50----(2)
solving 1 & 2 eqns
we get,m=56 - 10 years agoHelpfull: Yes(4) No(0)

You are right data given are impossible but whatever is question, solution should be according to that. No need to think about data - 10 years agoHelpfull: Yes(2) No(0)
- Present age of Mohan--->M and Present age of Grandmother-->G
G-M=6......1
Now,G-50=2(M-50)
=>2M-G=50.........2
Putting the value of G from equ 1 to equ 2 we get
2M-6-M=50
M=56
So,present age of Mohan is 56 - 10 years agoHelpfull: Yes(2) No(0)
- let age of grandmother = x yrs
then age of mohan=(x-6)yrs ( diffrn 6 given)
age 50 yrs ago,
grndmother= (x-50)yrs
mohan= (x-6-50)=(x-56)yrs
a/q,
x-50=2(x-56)
solve for x
u will get
x=62 yrs (grndmother's age)
mohan present age= (62-6) yrs= 56 yrs - 8 years agoHelpfull: Yes(1) No(0)
- m-g=6
g=2m
(g-50)=2*(m-50)
we know that g=m-6..
(m-6-50)=2*(m-50)
solving..m=44 - 10 years agoHelpfull: Yes(0) No(6)
- 56 y becaz before 50 years gm age twice and difference also 6.
