Solution
The correct option is B 250 mL
Total water in the bottle = 1 litre = 1000 mL
Water that Rajni drinks in the morning = Quarter litre = 250 mL
Water that Rajni drinks in the afternoon = Half litre = 500 mL
Total water drank by Rajni = 250 mL + 500 mL = 750 mL
Water left in the water bottle = 1000 mL - 750 mL
= 250 mL
Total water in the bottle = 1 litre = 1000 mL
Water that Rajni drinks in the morning = Quarter litre = 250 mL
Water that Rajni drinks in the afternoon = Half litre = 500 mL
Total water drank by Rajni = 250 mL + 500 mL = 750 mL
Water left in the water bottle = 1000 mL - 750 mL
= 250 mL
