Ques:- A wizard named Nepo says “I am only three times my son's age. My father is 40 years more than twice my age. Together the three of us are a mere 1240 years old.” How old is Nepo?
Recent Answer : Added by Chetan On 2021-07-16 09:53:52:

360 years old
Nepo’s son age = x
Nepo’s age = 3x
Nepo’s father age = 2*3x + 40

x + 3x + 6x + 40 = 1240
10x = 1200
x = 120

Nepos age = 3* 120 = 360 years
