At present, Suresh’s age is twice the age of his daughter. After 6 years from now, the ratio of the ages of Suresh and his daughter will be 23 : 13. What is the present age of Suresh?
Note
Let the daughter's age be x years.
Suresh's age = 2x years.
⇒ 13 (2x + 6) = 23 (x + 6)
⇒ 26x + 78 = 23x + 138
⇒ 3x = 60
⇒ x = 20.
Present age of Suresh = 2x years = (2 × 20) years = 40 years.
