According to a car dealer's sales report, 1/3 of the cars sold during a certain period were sedans and

1/5 of the other cars sold were station wagons. If N station wagons were sold during that period, how many sedans, in terms of N, were sold?

correction in the question -> it is 1/5 and not 1.5

now let us say there are X cars

and # of cars sold are Y

sedans sold -> Y/3

station wagons sold =1/5 of the other cars-> 1/5 *2/3* Y=2/15 Y

but 2/15 Y= N or Y =15/2 N

thus # of sold sedans = Y/3 => (15/2 N )/3 =>5/2 N

thus D
