Previous Question: There are 30 cards. Each card has a single number written on it, such that all the integers from 1 to 30 are represented in the cards. Two cards (which have numbers a and b written on them) are arbitrarily chosen, and are removed from the pack. The above two cards are replaced with a single card, on which the number (ab + a + b) is written. This constitutes one operation. After 29 such operations, what will be the number written on the sole surviving card?1) 31! âˆ’ 1 2) 15 Ã— 31 3) 30! âˆ’ 1 4) 31! + (15 Ã— 31) 5) 30! + (15 Ã— 31) âˆ’ 1
