Question

How many ways 5 children be arranged in
a row such that boy Yusuf occupies the first place
& girls Geeta & Meena are
always together.​

Answer 1

answer

Ram → R Shyam → S

No. of ways of arranging in which R & S together =4!×2!=48

No. of ways of arranging in which R & S not together = Total ways to arrange − No. of ways of arranging in which R & S together.

=5!−4!×2!

=120−48=72.
