The Ball Challenge
Tennis Ball = 2
Explanation
Equation 1: 10 + 10 + 10 = 30 (Rugby Ball = 10)
Equation 2: (5 x 5) + 10 = 35 (White Baseball = 5)
Equation 3: (4 x 4) + 10 = 26 (Green Baseball = 4)
Let us assume that the value of ‘Tennis Ball’ be ‘T’;
Equation 4:
5 + (4 x T) + 10 = 23
=> 4T + 15 = 23
=> 4T = 23 – 15
=> 4T = 8
=> T = 8/4
=> T = 2
Therefore; the value of ‘Tennis Ball’ = 2.

– Grammar rules, the first sentence is in the present tense. So when it says he has 6 eggs, he has 6 eggs. The other sentences are in the past tense. (This is the officially correct answer ….)However:– The exact answer is 2 because if two eggs were broken from 6 eggs there will be 4 more and then she cooked and ate two extra eggs. 6-4=2 so there will be 2 more left– There are four left… he broke two, cooked the same two, and ate the same two.
