sorry i cant tell u something new...there is only 1 way..start with Ncerts class 6 and dont read it like a novel(just because it is easy)
Sir, in the first question, I understood the question like this: There's an additional 2% increase on the 6% increase. So, I took it as 100 + 6% = 106, 106 + 2% = 108.12. But you took it like 100 + 8% = 108. Which is correct?
sir the answer of question at 7.35 is 27.5% because 8.25/30 =27.5% which is in the option. so we can't take 38.25 as 39.
My mistake sir I haven't see the entire video sorry !!!!

Read %age as fraction. Hope your doubt is cleared. Whenever it is not given we assume the respective ratio.
