Great effort. Thanks. Please look at Q 58. I don't believe it is correct. It should have been product of mode and median or something else...Mean is a very large number since sum of the series is 1 + 2*2 + 3*3*3 + 4*4*4*4 + .....+ 9*9*9*9*9*9*9*9*9

abt q 58: the sum is not quite large as there is formula to calculate it : [n(n+1)(2n+1)]/6 where n = 9!!! then divide by n(n+1)/2 again n is 9 this will giv u the mean !! den multiply by mode which is 9!! the answer is 57:)
