Dear student,
R is not sitting at extreme end.since P is 7th on the left of Q. R, who is 20th in the row from left, is 7th on the right of Q. If S, who is third on the right of P, is 20th in the row from right
_ _(6) _ P_(2) _ S_ (3)_ _Q _ _ _(5) _ _R _ _ (9)_ _ _ _
So total number of boys in the row = 6+P+2+S+3+Q+5+R+8=28
Thank you
