Question

please explain and answer..... ​

Answer 1

Answer:

Option D

Step-by-step explanation:

Let x be the number of keepers.

Total number of heads of 50 hens, 45 goats ,8 camels and x keepers =50+45+8+x=103+x

Total number of legs of 50 hens =100

Total number of legs of 45 goats =180

Total number of legs of 8 camels =32

Total number of legs of x keepers =2x

Total legs = 100+180+32+2x=312+2x

Total number of feet is 224 more than 312+2x

∴ 103+x=312+2x−224

∴ x=15

Answer 2

Answer:

Let the number of keepers be x.

Then, total number of feet

= 2×50+4×45+4×8+2x

= 100 + 180 + 32 + 2x

= 2x + 312

Total number of heads

= 50+45+8+x

= 103 + x

Now, (2x+312) = (103+x)+224

=> x = 15

∴ Option d) 15 is the answer
