Question 464107

To arrange them firstly find the number of ways to select 3 girls that will 
between Ushna and Manood. 

number of ways = 5C3  

( select 3 girls out of 5 girls i.e except Ushna and Manood from total 7)

number of ways to arrange these 3 girls = 3!

number of ways to arrange ( 2 other girls + Ushna & Manood) = 3!

i.e  here Ushna & Manood is single entity.


number of ways to arrange Ushna & Manood on their position = 2!

i.e only interchange of their position.


required number of ways = (5C3) x (3!) x (3!) x (2!)
