| Total value |
4 u |
2 u + 8 |
6 u + 8 |
Number of rhinoceros = 1 u
Number of flamingos = 1 u + 4
Number of rhinoceros' legs
= 4 x 1 u
= 4 u
Number of flamingos' legs
= 2(1 u + 4)
= 2 u + 8
Total number of legs
= 4 u + 2 u + 8
= 6 u + 8
6 u + 8 = 92
6 u = 92 - 8
6 u = 92 - 8
6 u = 84
1 u = 84 ÷ 6 = 14
Number of flamingos
= 1 u + 4
= 14 + 4
= 18
Answer(s): 18
