If x and y are integers greater than 1 , is x a multiple of y
1)3y^2+7y =x
2)x^2-x is a multiple of x
OA is A
1)3y^2+7y =x
2)x^2-x is a multiple of x
OA is A
The answer is A
We need to find if x/y is an integer or not??
(1) 3y^2+7y=x , substitute this value in x/y we get, 3y^2+7y/y or y(3y+7)/y and this will result only in an integer as y gets cancelled on the numerator and the denominator!! SUFFICIENT.
(2) says nothing about y so INSUFFICIENT.
Did u get me gmatrant??
