Assume a number for the number of donuts produced in 1996 to make calculations easier.
If that number were 200.
In 1997, there will be an increase of 37.5%, making the total number of donuts produced 275.
In 1998, there will be an decrease of approximately 11.1%, making the number of donuts around 244.2.
In 1999, again since there is a decrease of 10%, the number of donuts is around 220.
So, essentially, there is a 10% increase in the donuts from initial number of 200(in 1996) to 220 in 1999.
Coming back to the problem, it has been given that the donuts produced in 1996 is 13680.
So the number of donuts that are produced in 1999 : 13680+1368(10%) = 15048(Option C)

1996 - 13680 (assume x)
1997 - (11/8)*x (37.5 is 3/8)
1998 - (11/8)*(88/99) (Recurring to fraction conversion)
1999 - (11/8)*(88/99)*(90/100) (90/100 is 10% less than )
On solving you get (11/10)*x
(11/10)*13680 = 13680+1368 = 15048 (Only one answer ended with 8 so not necessary to solve complete)
