Question 1:
A zookeeper counted the heads of the animals in a zoo and found it to be 100. When he counted the legs of the animals he found it to be 340. If the zoo had either pigeons or elephants,how many pigeons were there in the zoo?
A. 45
B. 30
Feedback Total number of legs = 4x + 2(100-x) = 340
4x + 200 – 2x = 340
2x = 140
x = 70
Total number of legs = 4x + 2(100-x) = 340
4x + 200 – 2x = 340
2x = 140
x = 70
P = 100-70 =30P = 100-70 =30
4x + 200 – 2x = 340
2x = 140
x = 70
Total number of legs = 4x + 2(100-x) = 340
4x + 200 – 2x = 340
2x = 140
x = 70
P = 100-70 =30P = 100-70 =30
C. 70
D. 50
