Question

tinas mother is three times as old as tina and four times as old ss tinas sister meena .meena is three years younger than tina .how old are tina meena and their mother

Answer 1

let tina's,her mother's and her sister's age be x,y,z respectively.
given that,
y=3x-------(1)
y=4z-------(2)
and,x=3-z------(3)
z=3-x-------(4)
putting value of x in eq. (2),we get
y=4(3-x)
y=12-4x------(5)
subtracting (5) from (1)
0=12-x
(x=12) so, tina's age=12

from eq.(4)
z=3-12
(z=9)so, Meena's age=9
from (1)
y=3×12
(y=36)so, tina's mother's age=36
