Technically or logically it is possible only once. As if you subtract 5 from 25 at first te result will be 20. Now, you can't subtract 5 from 25 since the left number is 20.   But if you go mathematically, it can be done infinite times and only 5 times without going into the negatives.

Let the required number be 'X' Condition 1 :   XX = 2X  => 2X2 = X => X = 12   Condition 2 : X × X = X2=> X = 12   Therefore, 12 is the number which becomes double when it is divided by itself and becomes half when it is multiplied by itself.

Answer: C) [6 + (261/315)] days Explanation: After day 1, A finishes 1/9 of the work. After day 2, B finishes 1/7 more of the total work. (1/9) + (1/7) is finished. After day 3, C finishes 1/5 more of total work. Total finished is 143/315. So, after day 6, total work finished is 286/315.   Now remaining work =  29 /315   On day 7, A will work again    Work will be completed on day 7 when A is working. He must finish 29/315 of total remaining work.   Since he takes 9 days to finish the total task, he will need 261/315 of the day.    Total days required is 6 + (261/315) days.
