Answer 1

Given table is given below

The relationship between the number of crocodiles and the number of alligators is not proportional across all lakes. Only two of the lakes have crocodiles and alligators in the same proportion. Which two lakes are they?

lake A and lake B

lake B and lake C

lake A and lake E

lake C and lake D

Answer : lake A and lake E

Lake ---> Crocodiles ---> Alligators ---> Ratio

A ---> 4 ----> 5

B ---> 21 ---> 35

C ---> 3 ---> 9

D ---> 6 ---> 16

E ---> 24 ---> 30

The ratio of A is 4: 5

B is 21: 35 = 3 : 5

C is 3 : 9 = 1 : 3

D is 6 : 16 = 3 : 8

E is 24: 30 = 4 : 5

Lake A and E has the same ratio 4: 5
