Answers
Solution:
The given numbers are 427, 476, 562, 460, 582, 592, 530 and 535.
Let us check the given conditions one by one and exclude numbers which do not satisfy the conditions, from the given list.
Condition 1. I am not a multiple of 10
The numbers which are multiple of 10 are 460 and 530. So we exclude them from our list.
The remaining numbers are 427, 476, 562, 582, 592 and 535.
Condition 2. My tens digit is a multiple of 3
The numbers which have multiple of 3 in tens digit are 562, 592 and 535. So we exclude the numbers 427, 476 and 582.
The remaining numbers are 562, 592 and 535.
Condition 3. If you round me nearest 100, I become 500
The numbers 562 and 592 become 600 when both numbers are rounded off to the nearest 100. The only number that becomes 500 when rounded off to the nearest 100 is 535
Answer: I am 535.
