The weight of moisture is 82% of 1 ton or 1000kg, that is 82*1000/100=820kg.

Weight of the remaining portion =1000-720=180. Now this remains constant in weight even after moisture reduces, but now becomes 100-70 or 30% overall.

So 180=30% of new weight. Thus new weight = 180*100/30=600

Given: The fruit in a box weighs a ton and has a moisture content of 82.0%. After some time under the sun, moisture content has dropped to 70%.

Asked: What is the current weight of the fruit in kg?

Before evaporation: -
Weight = 1000 kg
Moisture = 820 kg
Other = 180 kg

After evaporation: -
Other = 180 kg
Weight = 180/30% = 18000/30 = 600 kg

IMO C
