Question 363486
let the age of raki =  r
and the mother's age = m
raki is 26 years younger than her mother
so we have 
r = m-26
in 9 years the age of raki = r+9
and the mother's age in 9 years would be m+9
in 9 years, her mother will be twice as old as raki.

so 
m+9 = 2(r+9)
but we have r  = m-26
let us plug in this in the equation above
m+9 = 2(m-26 +9)
m+9 = 2(m-17)
m+9 = 2m -34
subtract m on both sides
m+9-m = 2m-34-m
9 = m-34
add 34 on both sides
9+34 = m-34 + 34
so m = 43 
so mother's present age = 43 years
and raki's present age is
43-26=17 years
