Answer 1

.Step 1: Finding the quantity of total water

Water in first tank $=$$989.85$$\text{liters}$

Water in second tank$=$$1\text{090.89 liters}$

Total quantity of water shopkeeper bought

$=$$989.85$$\text{liters}$$+$$1\text{090.89 liters}$

$\text{=2080.74 liters}$

Step 2: Finding the quantity of water left with shopkeeper

He used $\text{768.065 liters}$ of water.

Water left with shopkeeper $=$Total water $-$ Water used.

So, water left with shopkeeper$=2080.74-768.065$

$=1312.67\text{5 liters}$

Hence, the shopkeeper is left with $1312.67\text{5 liters}$ of water.
