What is the ratio of elephants to monkeys in a zoo, if number of elephants is less than 20?
(1) Monkeys are 20 more than elephants in number.
(2) Number of elephants is a factor of 20, and more than 5.
Let the number of elephants be E and number of monkeys be M
Given data: E < 20
We need to find out the ratio \(\frac{E}{M}\)
1. M = E + 20
Case 1: E = 2, M = 22, Ratio is 11:1
Case 2: E = 4, M = 24, Ratio is 6:1
(Insufficient)2. E is a factor of 20 and E > 5
E could take values of 10. but without any information about M,
we cannot find the ratio
(Insufficient)Combining the information present in the statements,
E = 10 and M = 30 and we have a ratio \(\frac{E}{M} = \frac{1}{3}\)
(Sufficient - Option C) _________________
