Potatoes

For three days, the store sold 1400 kg of potatoes. On the first day, they sold 100 kilograms of potatoes less than on the second day. On the third day, three-fifths of what they sold the first day. How many kgs of potatoes are sold every day?

Correct answer:

a =  500 kg
b =  600 kg
c =  300 kg

Step-by-step explanation:

a+b+c=1400 a = b100 c = 3/5 a = 3/5 (b100)  (b100)+b+3/5 (b100)=1400  13b=7800  b=137800=600  b=600  a=b100=600100=500 kg
c=1400ab=1400500600=300 kg
