As shown in the figure the path difference can be given by 
d C o s theta
where d=3a
For maximas path difference increment x equals n lambda
d C o s theta equals n lambda o r 3 a C o s theta equals n a over 5 C o s theta equals n over 15 F o r space o n e space q u a r d a n t 0 less-than or slanted equal to theta less-than or slanted equal to 90 T h e r e f o r e C o s theta less-than or slanted equal to 1 H e n c e n less-than or slanted equal to 15
So in one quardant we can have 15 maximas 
therefore the total number of maximas possible is 60
