Grapes harvesting

The foreman harvested grapes for three days, a total of 2,510 kg. On the second day, they peeled 480 kilograms less than the first day, the third day, and 25% more than the first day. How many kilograms of grapes did the part-timers pick the second day?

Correct answer:

b =  440 kg

Step-by-step explanation:

r=100%+25%=1+10025=1.25  a+b+c=2510 b = a480 c = r a  a+(a480)+r a=2510 a+(a480)+1.25 a=2510  3.25a=2990  a=3.252990=920  a=920  b=a480=920480=440=440 kg  Verifying Solution:  c=r a=1.25 920=1150 kg s2=a+b+c=920+440+1150=2510 kg
