My answer is 426..

here it goes..

total number of arrangements using 6 persons is 6!= 720 ways,.
Tom cant be in first postion

therefore possible arrangements are 6!-5! = 600 ways

Jerry cant be position 2 in 5! = 120 ways

Tom occurs in position 1 in 24 (4!) ways which already included in the first case above

therefore the arrangements are 600-120+24 = 504 ways ( 600- (5!-4!) )

Donald cant be 3rd postion in 5! = 120 ways
Bu A occurs in postion 1 in 24 (4!) ways and B in position 2 in 18 ways ( 4!-3!)

there fore possible arrangement are 504-120+24+18 =426 ways..


hope its clear,,,

Any takers for this .. though i got it right ...i found it to be a very long and tedious procedure wherein anyone can go wrong during the exam tension..

Any other shorter method on this will be highly Appreciated!!!
