Sulah Hudebya _______ Hijri ma huwa. 6th Hijri ma

Mother age is 3 time greater then daughter age. After four year the sum of the ages daughter and mother is 60. What is the age of mother? Mother age is 39. (

Let

Daughter age = x
Mother age = 3x

After 4 years

Daughter age = x+4
Mother age = 3x+4

After 4 years, the sum of ages is 60, hence

  (x+4)+(3x+4)=60

   4x+8=60

   4x = 60 - 8

   4x = 52

   x = 13

Hence, Mother Age = 3x

             Mother age = 3(13) = 39
)
or
(Beti ki age 13 year 
13 ×3 = 39 
39 is mother age ...

After 4 year 
Beti ki age 13+4 =17
Mother age 39+4 = 43
17+43= 60)
