Answer:
17
Explanation:
We have : The hand = 2 x 2 = 4
22 = 2 Ice creams + the hand => 2 ice creams = 22 - 4 = 18 => 1 ice cream = 9
2 girls = The hand + 4 = 4 + 4 = 8
4 girls - 2 = calendar => 16 - 2 = calendar => calendar = 14
Ice cream = 4, calendar = 14 => ice cream + calendar - 1 = 14 + 4 - 1 = 17.
