The shark are fed three times a day. During the morning feeding 2/15 of a ton of the fish is fed. During the afternoon feeding the weight of fish fed will be 1/15 of a ton more than the fish fed during the morning. If the total weight of fish fed in a day is 1/2 of a ton how much is fed during the feeding at night?

1/6 of a ton.

Step-by-step explanation:

In the morning, 2/15 of a ton is fed to the fishes.

In the afternoon, weight of the feed will be 1/15 of a ton more than the fish fed during the morning.

i.e. 2/15 +1/15 = 3/15

If the total weight of fish feed in a day is 1/2 of a ton.

Therefore:

Morning Feed + Afternoon Feed + Night Feed = ½

2/15 + 3/15 + Night Feed = ½

5/15 + Night Feed = ½

⅓ + Night Feed = ½

Night Feed = ½ - ⅓ = 1/6

Therefore, in the night, the fish are fed 1/6 of a ton.
