Bob can eat 27 chocolates in an hour. Alice can eat 2 chocolates in 10 minutes, and Kelly can eat 7 chocolates in 20 minutes. How long will it take them to share and eat a large box of 120 chocolates whilst watching a movie?

• Bob can eat 27 chocolates in a hour,
  Alice can eat 2 chocolates in 10 minutes or 12 choc in 1 hr
  , and Kelly can eat 7 chocolates in 20 minutes or 21 chocs in 1 hr.
  
  Three together can eat 27+12+21 = 60 choclates in 1 hr .
  it take them 2 hrs to share and eat a large box of 120 chocolates whilst watching a movie

• total no of chocolates consumed in 1 hr by bob,alice n kelly r 27,2*6=12,7*3=21 respectively..
  this means total no of chocolates consumed in 1 hr = 60
  so 120 will b consumed in 2 hrs..
