If there are 50 hens, 40 goats, 30 camels and some watching men. If number of legs are 640 more than that of heads. Then find the no. of watching men??

Read Solution (Total 3)

answer : 380 men,
sol: as, total number of head in animal is 120, and total no of leg of animal is (50*2)+(40*4)+(30*4)= 380. present diff between , leg and head is 380-120=260.
required difference is 640, so additional difference required is 640-260=380. so this difference can creat by adding 380 heads of men s.o 760 legs..and then their difference will be 380. so the answer is 380 men.
