Question

You have 10 blank cards. On each card, you can write either 1,3 or 5. How can you obtain a total sum of 25.

Answer 1

n! = n×(n-1)×(n-2)×(n-3).......                                                                                          then 3! = 3×2×1= 6                                                                                                              ∴ the answer is 3!+3+5+5+1+1+1+1+1+1= 25.
