Answer:
Only one Zoo has exactly 42 lizards
Step-by-step explanation:
If you check out the attached diagram , you will observe that there is a separation using a vertical line
In the diagram also we have been provided with a key which was explained as :
2|0 = 20 lizards
On the left hand side, we have number ranging from 0 - 6 arranged in a vertical form. On the right hand side we almost have numbers that are arranged in front of each number horizontally
Let me further explain the attached diagram
It is important to note that the numbers arranged vertically on the left are in the units of tens. Hence, using the given key :2l0
0|
1|
2| 0 6 8 8 8
This means , we have 20 lizards in one zoo, 26 lizards in one zoo, 28 lizards in 3 zoos
3| 0 2 6 6 7 8
30 lizards in one zoo, 32 lizards in one zoo, 36 lizards in 2 zoos , 37 lizards in one zoo and 38 lizards in one zoo
4| 1 2 6 6
We have 41 lizards in one zoo, 42 lizards in one zoo, and 46 lizards in two zoos

Based on the explanation given above, we can see that only one Zoo has exactly 42 lizards
