Hello sr in this question 11 new trick is available for example sum of (1 to 6) is equal to we have do that with 2nd trick for that first select first digit and last digit here 1+6=7 and multiply with total count of that number here 6 is total number is 6 and 6*7 is 42 and divide that number into 2.... 21 is the answer 1+2+3+4+5+6= 21

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..

Sir in question no. 11 We can also use the Sum of n natural number formula from arithmetic Progression ?

[soulscreation]

Sol. 11) n/2*(a+l) = (110 - 91+1)/2 * (91 + 110) = (110 - 90)/2 * (201) = 2010. @S Chand Academy OR (90 = 90*20 + 20*(20+1)/2 = 1800 + 210 = 2010 #S Chand Academy

In question 24, shouldn't we subtract 28 twice? One to avoid double counting and one to remove answers divisible by 35. So shouldn't answer be 285?

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

[vijay]

1 is composite number or prime number because it has only 1 factor

[jarupulaganesh]

At 13th question we also use division rule...(1+4)-(0+3)=2...So answer is 2..
