Question 21
Back to Exercise
In a caravan, in addition to 5o hens, there are 45 goats and 8 camels with some keepers. If the total number of feet be 224 more than the number of heads in the caravan, the number of keepers is
- A 5
- B 8
- C 10
- D 15 Correct
Correct Answer: Option D
Let the number of keepers be x. Then,
Total number of feet = 2 × 50 + 4 × 45 + 4 × 8 + 2x = 2x + 312.
Therefore (2x + 312 ) = ( 103 + x) + 224 or x = 15.
