Neeta bought 5.5 ltr of mango juice. She and her friends consumed 3 ltr 925 ml of the juice. How much juice is left with her?
1 ltr 575 ml
1 ltr 275 ml
1 ltr 375 ml
1 ltr 475 ml
1 ltr 575 ml
Convert all to ml: 5.5 ltr = 5500 ml and 3 ltr 925 ml = 3925 ml. Subtract 3925 from 5500 to get 1575 ml, which is 1 ltr 575 ml.
Total mango juice = 5.5 ltr. Consumed mango juice = 3 ltr 925 ml.
Remaining=TotalтИТConsumed
Convert all to ml: 5.5 ltr = 5500 ml and 3 ltr 925 ml = 3925 ml. Subtract 3925 from 5500 to get 1575 ml, which is 1 ltr 575 ml.
Confusing decimal conversion: 5.5 ltr is 5500 ml, not 5050 ml, and failing to convert the mixed units of the consumed amount correctly.
Convert total quantity to ml
Since 1┬аltr=1000┬аml, convert 5.5┬аltr to ml.
5.5├Ч1000=5500┬аml
Convert consumed quantity to ml
Convert 3┬аltr┬а925┬аml to ml by adding 925 to 3├Ч1000.
3000+925=3925┬аml
Subtract consumed from total
Subtract the consumed quantity from the total volume.
5500тИТ3925=1575┬аml
Convert back to ltr and ml
Convert 1575┬аml back into liters and milliliters by separating thousands.
1575┬аml=1┬аltr┬а575┬аml
A is correct because the difference between 5500 ml and 3925 ml is 1575 ml, which equates to 1 ltr 575 ml.
This is a basic metric conversion problem frequently seen in speed/distance and weight problems; always convert to the smallest unit (ml, g, m) before performing arithmetic.
