In a store there were 100 kg of berries. An analysis showed that the moisture in the berries was 99%. Determine the total weight of the berries when, by a later analysis, the moisture had become 98%.

Solution

Hence wight of moisture=0.99*100=99 kg

Hence dry weight of berries =1kg

Let weight with 98% moisture be W

Hence, 2% of W=1 kg

0.02W=1

W=50 kg

Total weight is now 50 kg
