    Problem 9:-xi=1 implies that (n-1)=1 or n=2,but it is mentioned that n>=3…I think there will be no solution….if you consider none of the values to be equal….you get x1xn=x2xn-1=…..=1….plugging in,we have x1=xn,x2=xn-1,which are contradictions..hence all values must be equal..which again results in n=2..another contradiction…thus,no solution……I might be wrong,you have the license to laugh at me…..

    Hello Amit sir, I am aditya narayan sharma (a high school student) . I guess in Q7 the answer should be 4900 as it should be n(n+1)(2n+1)/6 , a tiny hand typo rather.

    sir I think in qs n. 7 the limits shud be from 0 to 23 as (i,j)<=24 so smallst square can be of unit 1 . we can choose 23 such lengths . i may be wrong too so kindly clear this doubt
