Question

A three digit number consists of 9, 5 and one more number. when these digits are reversed and then subtracted from the original number the answer yielded will consist of the same digits arranged in a different order. what is the third digit?

Answer 1

Given the condition that when these digits are reversed and then subtracted from the original number the answer yielded will consist of the same digits arranged in a different order.

If we take the other no. to be 1,
no. becomes 951
951 - 159 = 792

If we take the other no. to be 2,
no. becomes 952
952 - 259 = 693

If we take the other no. to be 3,
no. becomes 953
953 - 359 = 594

If we take the other no. to be 4,
no. becomes 954
954 - 459 = 495

Hence the other number is 4.
