The metre skips all the numbers in which there is a 5, From 0000 to 0099, 5 occurs 10 times in the tens place and 10 times in the units place, (which includes the number 55)
∴ It occurs in a total of 10 + 10 − 1 numbers i.e, 19 numbers.
Similarly, from 0100 to 0199, from 0200 to 0299, 0300 to 0399 from 0400 to 0499, 0600 to 0699, ... 0900 to 0999. It occurs in 8(19) numbers. From 0500 to 0599, there are 100 numbers. The micro nanometer reading could change from 0499 to 0600.
Total number of numbers skipped from 0000 to 0999= 19(9) + 100 = 271
Similarly, from 1000 to 1999 and from 2000 to 2999, 271 + 271 numbers are skipped.
Finally, 3005 and 3015 are also skipped.
Finally, 3005 and 3015 are also skipped.
∴ Total number of skips = 271(3) + 2 = 815
∴ Actual pressure = 3016 − 815 = 2201
