Given:

Initial water in tank = 300 ltr

Water used = 87 ltr 225 ml

Formula used:

Water left in tank = Initial water - Water used

Calculation:

Convert 87 ltr 225 ml to liters:

87 ltr 225 ml = 87.225 ltr

Water left in tank = 300 ltr - 87.225 ltr

⇒ Water left in tank = 212.775 ltr

Convert 212.775 ltr to liters and milliliters:

212.775 ltr = 212 ltr 775 ml

∴ The correct answer is option (1).
