Four children made the following statements.
Aria : Jayden is 2 kg heavier than Natalie.
Natalie : Our masses are in consecutive order.
Maya : The average of Aria's mass and my mass is 34 kg.
Jayden : I am the heaviest.

What is the total mass of Maya, Jayden and Aria ?
Order of the mass of 4 children:
_____ , Natalie, _____ , Jayden (Heaviest)

Total mass of Maya and Aria
= 2 x 34
= 68 kg

For Maya and Aria,
Mass of the lighter one = 1 u
Mass of the heavier one = 1 u + 2

Total mass of Maya and Aria
= 1 u + 1 u + 2
= 2 u + 2

2 u + 2 = 68
2 u = 68 - 2
2 u = 66

1 u = 66 ÷ 2 = 33

The mass of the four children in consecutive order is 33, 34, 35 and 36.

Total mass of Maya, Jayden and Aria
= 33 + 35 + 36
= 104

Answer(s): 104 kg
