Question: Steve has 10 liters (L) tank filled with water. He wants to transfer the water in few smaller tanks of following sizes: 2 talks of 1.5 liters, 3 tanks of 750 ml and 6 tanks of 500 ml. Please calculate the amount of water left in 10 L tank after filling all the smaller talks ?
Answer: This is a pretty simple question. First we need to add capacity of all the smaller tanks. If the addition value of all the smaller tanks is less that 10 L, then subtract this value (addition value of smaller tanks) with 10 L and remaining value will be the answer. That is water left in the bigger tank.
On the other hand, if the addition value of all the smaller tanks will be greater than 10 L, then after subtraction, we will identify amount of water left to fill the all the smaller tanks.
Let us calculate capacity of all smaller tanks, which is:
1.5 liters x 2 tanks = 3 liters
750 ml x 3 tanks = 2250 ml = 2 liters and 250 ml
500 ml x 6 tanks = 3000 ml = 3 liters
Now add all of the tanks, that is: 3 liters + 2 liters 250 ml + 3 liters = 8 liters and 250 ml, which can also be written as: 8 L and 250 ml
Now we will subtract 8 liters and 250 ml from 10 liters to calculate the rest amount of water in the bigger tank.
So, 10 L − 8 L and 250 ml
Or, 10,000 ml − 8250 ml
= 1750 ml or 1 liter and 750 ml will be remaining in the 10 L tank
