Answer 1

Solution :-

→ Position of Paul from left end = 21

→ Position of Sam from right end = 15

also, in last line it is given that, Sam is third to the right of Paul .

then,

→ Position of Sam from left end = 21 + 3 = 24

therefore,

→ Total people in the queue = Position of Sam from right end + Position of Sam from left end - 1

→ Total people in the queue = 15 + 24 - 1

→ Total people in the queue = 39 - 1

→ Total people in the queue = 38 (Ans.)
