There is a 450 liters solution of sugar and water in a vessel which contains 20% sugar how much sugar should be mixed in the mixture so that the sugar becomes 25%?
Answer & explanation
Correct answer: option 1
In the mixture:
Sugar is 20% then water is 80%
In the new mixture,
Sugar is 25% then water is 75%
*In the process, sugar is added but water remains same.*
Therefore,
Water in Old Qty = Water in New Qty.
80% of 450 = 75% of New Qty.
New Qty. = 480 Litters
Hence,
Sugar added = 480 - 450 = 30
