no guys.........here order means that U should always come after E. now there are 4 possibilities. case I : when E occupies the first position, no. of words = 4! = 24 case II : when E occupies 2nd pos., no of words = 3*3*2*1= 18 case III : when E occupies the 3rd pos. , no of words = 3*2*2*1 = 12 case IV : when E occupies the 4th position, no of words =3! = 6
So, total no. of words possible = 24 + 18 + 12 + 6 = 60
