Hi,
Best way of doing this would be take numbers as n, n+1, n+2
so we have n+1+n+2 = n^2
n^2-2n-3 = 0
n^2-3n+n-3=0
n(n-3)+1(n-3)=0
(n+1)(n-3) = 0
n = -1 or 3
-1, 0 , 1
3, 4, 5
So answer is either 0 or 12
we have only 12 given in options
Cheers,
SVD

We can easily solve by taking common We have (x-y)2 = 10, x2-y2=2 Equation is (5x+5y)/(6x-6y), Taking 5 and 6 common in numerator and denominator we have 5/6 * (x+y)/(x-y) , Now multiply both numerator and denominator using x-y 5/6 * (x+y)(x-y)/(x-y)(x-y) = 5/6 * x2-y2/(x-y)2 = 5/6 * 2/10 = 1/6 Lot ...
