75 Arrangements
Step-by-step explanation:
Girl can secure 1st & 3rd, boy can secure 2nd position in : 6 x 5 x 5 = 150 ways ; As :
- 1st position holder can be chosen in 6 ways (among 6 girls)
- 2nd position holder can be chosen in 5 ways (among 5 boys)

The answer would be 26
Step-by-step explanation: (Broken down into 2 parts)
-PART ONE- solving (12-7) x (8-5) -7
(12-7) x (8-5) -7 (do whats in parentheses first)
(5)x (3) -7 (multiply 5x3)
15-7 (subtract)
ANSWER- 8
-PART TWO- solving (16-4) + (10 - 12 divided by 3)
(16-4) + (10 - 12 divided by 3) (do what is in parentheses)
12 + 10-4 (add)
22-4 (subtract)
ANSWER- 18
Now combine the two answers 18+8 and you get 26
Therefore, 26 is the final answer.
Hope this helps!!
