Question 935153
let x=sheela (m0ther)----present age 
y=daughter preent age 
(x-1)=4(y-1)--------a year ago---eq 1  
(x+6)=(y+6)+9-------6years hennce ----eq 2
x/y= required --------------?present 

@ equation 1 

x-1=4y-4
x=4y-3-----then substitute to eq 2
x+6=y+15
4y-3+6=y+15
3y=15-6+3
y=4-----------------daughter age 

then solve sheelas age 

x-1=4(4-1)
x=13

then...the ratio is x/y=13/4--------------------
