more men to work. In how many days will the remaining work be completed?
2. 1600 soldiers in a camp had enough food for 30 days. After 8 days, some soldiers left the camp and thus the
food lasted for another 32 days. How many soldiers left the camp?​

Answer 1

Answer:

1. no of employes a construction company need=300

ompany need=300 building the foot over the bridge in days=24

ompany need=300 building the foot over the bridge in days=24 more employees need to complete the construction=5

: the construction is completed in24-10=14

= the construction is completed in only 14 days

hence, 14 days are needed to complete the construction.

2. soldiers in the camp are=1600

food storage in the camp is for=30 days

soldiers left camp after=8 days

food lasted after some soldiers left=3w days

: soldiers left camp8÷1600=200

hence, 200 soldiers left the camp after 8 days.
