Ramu is now 32 years old and his son is 7 years old. In how many years, Ramu will be twice as old
as his son
Answers
Answer: 25 years old
Step-by-step explanation:
Age of Ramu= 32 years.
Age of his son= 7 Years.
Let after x years the age of Ramu will be 2y.
And after x years his son age be y.
32 + x = 2y ………….(eq.1)
7 + x = y …………..(eq.2)
32 + x = 2y
=> x = 2y - 32 ………….(1)
Putting the value of (1) on eq.2 we get,
7 + 2y - 32 = y
=> 2y - y - 25 = 0
=> y = 25
Thus from (eq.1)
7 + X = 25. ( Putting value of y)
=> X = 18
Thus after 18 years the condition will satisfy
Let's check whether the answer is correct or not.
After 18 years
Ramu = 32 + 18 = 50 years
His Son = 7 + 18 = 25 years. (Proved)Age of Ramu= 32 years.
