Fresh fruits contain 80% water, and dry fruits contain 15% water. How much dry fruits can be obtaine
Fresh fruit = Real Dry fruit (No water) + Water
Dry Fruit = Real Dry Fruit + Water
Hence 1 KG of Fresh Fruit = 200 grams of real dry fruit ( We counted water content of both fruit + Dry fruit).
Now 1000 grams of dry fruit has 15% water i.e. 150 grams of water.
Hence 1000 grams dry fruit has 850 grams of real dry fruit.
Thus 100 grams of real dry fruit is obtained from = (1000/850)*100 = 117.64 grams of dry fruit.
Hence dry fruit obtained = 68*0.2*1.1764 = 15.999 KG
End Note :
In layman’s terms, we find real dry fruit by taking 80% water out. Since we took water in dry fruit also out, we compensated it by multiplying it to 1.1764 to the real dry fruit obtained.
Remember we have to increase something to about 17.64% to compensate loss of 15%. Hence it always take higher percentage gain to make up for losses of similar gain. Loss in any shares price by 15% is equal to gain in 17.64% from the price it was dropped!!
Common example : 20% loss from 100/- is 80/-. But 20% gain from 80/- is just 96/-!. Hence to cover losses of 20%, market needs to grow to another 25% from the drop!
Hence loss is always more dangerous than gains. Never believe what your instinct say, trust the numbers.
