1-if(c-a=2 then can c=2a??
yes I have also the same doubt. c should be (2+a)?
If C-a=2, Then as “a” will change its sign from negative to positive while going to other side, so c=2+a not 2a.
PLEASE SHARE THE QUESTIONS PDF IF POSSIBLE.
plz see at 26:20
again if u interchange the tens and unit digits the no. remain same i.e. 411, so same number can not be counted two times.

Thank you ma’am for clearing my doubt
Isn’t the answer should be 280 rather than 300…
Bcz 9 groups of 20=180
And the one excluded group(500to600) of 100 numbers
Plz correct me
180+100 (u understood) now, U have 5 as unit digits between 500 to 600 -10 times and 5 at tens place between 500 to 600- 10 times..so total times digit 5 used is…180+100+20=300
