Therefore, the store sold 600kg of sugar on the third day.

Step 4: Subtract the total amount sold in two days from 2400kg to find out how many kilograms of sugar they sold on the third day. 2400kg - 1800kg = 600kg

Step 3: Add the kilograms of sugar sold on the first and second day to find out the total amount sold in two days. 840kg + 960kg = 1800kg

Step 2: Calculate how many kilograms of sugar they sold on the second day. 40% of 2400kg = 0.40 x 2400 = 960kg

Step 1: Calculate how many kilograms of sugar they sold on the first day. 35% of 2400kg = 0.35 x 2400 = 840kg
