Answer
To write the natural numbers between 500 and 600 which do not change if the digits are written in the reverse order we must have the same digit at the hundred's place and unit's place.
Hence, the required numbers are 505, 515, 525, 535, 545. 555, 565, 575, 585, 595.
Hence, the required numbers are 505, 515, 525, 535, 545. 555, 565, 575, 585, 595.
