Method 2
By doublet in mathematics, we mean a number of two digit with similar digits. In number system we have 90 two digit numbers. In the set of two digit numbers, we have 9 doublets such as 11 , 22 , 33 , 44 , 55 , 66 , 77 , 88 , 99
From 1 to 100 we have 100 numbers and 9 doublets in there. So, the percentage of doublet between 1 to 100 is (9/100)*100%
= 9%
Answer: 9% doublet present in between 1 to 100.
