Let Paul’s age = x years Raju’s age = 2x To get Kai’s age, We have to subtract 6 from 2x as Kai is 6 years younger than Raju Kai’s age = 2x -6 Sum of their ages = 29 x + 2x + 2x- 6 = 29 5x - 6 = 29
Add 6 to both sides 5x = 29 + 6 5x = 35 Dived both sides by 5 x = 35/5 x = 7 Paul’s age = 7 years Raju’s age = 2*7 = 14 years Kai’s age = 14 - 6 = 8 years
