Question

Based on first three equations what would be the value of the forth equation in the given image?

Answer 1

3 Couples + 3 Bag = 30
Couple + Bag = 10
3 Suitcase = 15
Suitcase = 5
4 Bags = 24
Bag = 6
Couple = 10 - 6 = 4

Final Equation: Bag + 2*Suitcase *Couple => 6 + 2*5*4 = 6 + 40 = 46.

Answer 2

16, 26, or 36, There is a black scarf in the 3rd figure on row #1. That has to accounted for:
My solution: Briefcase = 5 and backpack = 6. On the top row, subtract 6 points for each backpack, and the 3 couples plus the scarf = 12. Therefore the couple has to be either 1, 2, or 3.

Couple = 1, scarf = 9 - total = 12. Solution #1: 6 + (10 x 1) = 16
Couple = 2, scarf = 6 - total = 12. Solution #2: 6 + (10 x 2) = 26
Couple = 3, scarf = 3 - total = 12. Solution #3: 6 + (10 x 3) = 36
