The owner of a local jewelry store hired two watchmen to guard his diamonds, but a thief still got in and stole some diamonds. On the way out, the thief met each watchman, one at a time. To each he gave 1/2 of the diamonds he had then, and 5 more besides. He escaped with two diamonds. How many did he steal originally? Choose the most appropriate option:
A) 50  B) 36  C) 25  D) None of these  E) Cannot be determined
Explanation :   Since, thief escaped with 1 diamond,   Before 2nd watchman, he had ( 2 + 5 ) x 2 = 20 diamonds.   Before 1st watchman, he had ( 20 + 5 ) x 2 = 50 diamonds.   50nswer : 50
