dear prashant

no of rows 2

let row a be filled with 5 husband so no of ways is equal to 25 and for eaach husband if his wife should not come in front or back then this implies that his wife can come in any place except his front place nd his back place then the no of ways his wife can be placed is 3 thus total no of ways is 3 *25= 75

please approve if its correct
