Previous Question: The number of times 2 occurs in 1000 to 9999. I came across two methods. Total 4 digit numbers that we can form is (9*10*10*10) Total 4 digit numbers that we can form with out 2 is (8*9*9*9) so 4 digit nos with 2 we can form (9*10*10*10)-(8*9*9*9) = 3168 OR Number of 2's at units place(1000 to 9999)=900 Number of 2's at tenths place(1000 to 9999)=900 Number of 2's at hundreds place(1000 to 9999)=900 Number of 2's at thousands place(1000 to 9999)=1000 therefore total number of 2's =(900+900+900+1000)=3700 Which is the right method? Next Question: n is an natural number,if n^3 is having 16 factors then how many factors does n^4 have?
