Let ravish age be x years and her daughter aarushi age be y years 7 years ago 7(x-7)=y-7 and three years from now 3(x+3)=y+3 7x- 49=y-7 7x-y=42...........1 considering second equation 3x+9=y+3 3x-y=-6.............2 subtracting 2 from 1 7x-3x -y-(-y) =42-(-6) 4x=48 x=12 putting x in any cases we get or lets put this in 2 equation 36-y=-6 -y=-42 y=42 so raveesh age is 42 years and aarushi agee is 12 year

Let present of raj=x sanjana=y x-7=(y-7)*7 x-7=7y-49 x-7y=-49+7=-42--------(1) and x+3=3(y+3) x+3=3y+9 x-3y=6---------(2) from 1 and 2 4y=48 y=12 and x=6+3*12 x=42
