If John produces n units of an item in t hours, what is the value of n?
(1) If John produces 4 more items per hour, he would take \(\frac{1}{4}\) lesser time to produce n units of the item.
(2) If John increases his rate of production by 25 percent, the time taken by him to produce n items would be 80 percent of the original time.
Statement 1: The equation becomes
((n/t)+4)/(n/t)= t/4
We cannot find n without the value of t.
Insufficient
Statement 2:
4/5 t= 80/100 t
Does not tell us anything
Insufficient
Statement 1 and 2 together does not say anything new.
