i bought new book s chanda quantitative aptitude best for all exam 😀🥳🥳🎉🎉💐🙏
in que no 103 , short cut is - 2004 divide by 4 will get remainder 3 (say golu). and unit digit of given question (13) is 3 (say bholu to three). hence bholu to the power golu is twenty seven i.e. (3 to power 3 is 27 ) so unit digit is 7. therefore seven is answer..
Thank you sir for your nice learning
Question 75 has a correction in the denominator, which should be 768 instead of 786. After this correction, the taught rule is applicable.
It would be great if he could have done whole the solved sums becz it helpd me alot to find multiple ways to solve

Kyuki 1000 bhi 5 se divisible hai...humlogo ko less than 1000 chahiye according to question isiliye 1 subtract kiya ...aur 7,35 se 1000 divisible nhi hai isiliye uske case pe 1 subtract ni kiya

Question 26 How x, x+2,x+4 will be 3 consecutive odd numbers... Put =0,2 or 4 then it becomes even . The correct expression should be 2n+1,2n+3,2n+5

hello brother here we consider x as an odd number and there is a prperty we all know that when we add even number to an odd number in that case the resulting no is an odd number for eg 1+2=3,3+6=9 and so on so it is correct

There's a formula for that one 1/6n x (n+1) (2n+1).... Substitute 9 in place of n you'll get 1/6 x 9 x 10 x 19 gives you 90x19 divided by 6 you'll get your answer For question 20 you have to know the Roman numerals, it's a late middle age of writing number, like( ii is 2)( iii is 3) (v is 5) here M is 1000, D is 500, C is 100, L is 50 , then arrange the sequence from big to small like so M>D>C>L
