if hot water takes = h mins to fill the tub

and cold water takes= c mins to fill the tub

Therefore working together they can complete in = \(\frac{{h*c}}{{h + c}}\) mins (This is general formula if we need to calculate the time required if two different individual work together)

Now back to ques, since denominator is same and h>c

Therefore QTY A > QTY B
