Answer 1

Answer:

32 Days

Step-by-step explanation:

For 32 days the remaining boys be fed.

Step-by-step explanation:

150 kg of wheat is stored for = 20 × 30  days

1 kg of wheat is stored for 1 person =  

                                                         =    = 4 days

after 30 kg of wheat was wasted, the remaining wheat = 150 - 30 = 120 kg

and 5 boys went home, so remaining boys = 20 - 5 = 15 boys

Therefore, 120 kg of wheat is consumed for 1 boy in = 4 × 120 = 480 days

Hence, for 480 days wheat is for 15 boys  =  

                                                                     = 32 days

For 32 days the remaining boys be fed.
