Question

the problem is to use the information given to figure our who will win the third round of tugofwar.
round 1 on one side are four acrobats, each of equal strength. on the other side are five neighborhood grandmas, each of equal strength. the result is dead even.
round2 on one side is Ivan, a dog. Ivan is pitted against two of the grandmas andone acrobat. again it is a draw. no winner.
round 3 Ivan and three of the grandmas are on one side and the four acrobats are on the other.
Who will win the third round? Prove it!
Explain your thinking.

Answer 1

a = pull of acrobat
g = pull of grannies
then 5 g = 4 a
and g = 5/4 a

i = 2 g + a
so
i = 14/4 a = 7/2 a

i + 3 g vs 4 a
7/2 a + 15/4 a vs 4 a
29/4 a vs 4 a
29/4 a vs 16/4 a
check my arithmetic
