First 2 bars showcases students who scored less than 20 so they are out of the required range, and rest 3 showcase students scoring between 20 - 50, as we have maximize the no. of students, we can assume all students in the range 40 - 50 have scored less than 46, which means max no. of students b/w 20 - 46 would be 7 + 6 + 6 = 19

Why 9x90x2-3k?
We have 9 digits=1.2.3.4.5.6.7.8.9
And we have 90 a two-digit numbers= 10..99
We need to find how many three-digit numbers to be combined with one-digit and two-digit number to be equal 1212
