Question

Q12. A wizard named nepo says "i am only three times my sons 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?

Answer 1

Assume
Son’s age to be X
So wizards age would be 3X
fathers age would be 40+6X according to question

X+3X+6X+40=1240
10X+40=1240
10X=1200
X=120
Therefore son’s age is 120
Nepo =3X
X =120
Therefore nepo’s age is 360years

Answer 2

Answer:

Let Nepo son's age = X years .

Nepo age = 3x

Nepo's Father age = 2(3x) + 40 = 6x+40

A/q,

x+3x+6x+40 = 1240

10x = 1200

x = 120 = Nepo son age .

Nepo age = 120*3 = 360 years .
