Sandeep filled water in 4/7 of an empty tank. Ramakat filled 1/4 past of the same tank. Then Umesh used 3/14 past of tank to water garden & the tank has maximum capacity of 560 liters, how much water is left in the tank now?

To find out how much water is left in the tank, we need to calculate the total amount of water that has been filled and then subtract it from the maximum capacity of the tank.

First, let's calculate the amount of water Sandeep filled in the tank. Sandeep filled 4/7 of the tank's capacity. To calculate the amount of water, we multiply the fraction (4/7) by the maximum capacity of the tank:

Water filled by Sandeep = 4/7 * 560 liters = 320 liters

Next, let's calculate the amount of water Ramakat filled in the tank. Ramakat filled 1/4 beyond (past) the already filled tank. So, the amount of water filled by Ramakat is 1/4 of the amount of water already in the tank:

Water filled by Ramakat = 1/4 * 320 liters = 80 liters

Now, let's calculate the amount of water Umesh used to water the garden. Umesh used 3/14 of the tank's total capacity:

Water used by Umesh = 3/14 * 560 liters = 120 liters

To find the amount of water left in the tank, we subtract the sum of the water filled and the water used from the maximum capacity of the tank:

Water left in the tank = Maximum capacity - (Water filled by Sandeep + Water filled by Ramakat + Water used by Umesh)
= 560 liters - (320 liters + 80 liters + 120 liters)
= 560 liters - 520 liters
= 40 liters

Therefore, there are 40 liters of water left in the tank.
