Question

In a camp with 45 athletes, there is enough
food to last for 25 days. After 5 days, 15 more
athletes join the camp. For how long will the
food last now?​

Answer 1

no. of athletes          no. of days

      45                            25

      60                            x

More no. of athletes--Less no. of days food will last

therefore, it is an inverse proportion.

k=a*b

k=45*25

=1125

when a= 60, b=x

k=60*x

1125=60x

x=1125/60

x=18.75

therefore, the food will last for only 18.75 days.

pls mark as brainliest!
