To Find; (a)how many problems can I solve in 10 minutes, assuming that the time in which I solve is proportional
(b)If you use 80 ml of water, how many spoons of sugar will you need for the recipe?
Solution; (a)
problems solved in 5 minutes=2
Problems solved in ten minutes=4
Hence four problems can be solved in 10 minutes
(b)20 volumes of water require sugar=3
80 volume of water requires sugar=12
Hence the number of spoons required is 12
