since we are given 1 equation, from which we can get dq + 24 = x (imagine q as quotient)any way Q is common in all our reactions. St.1 gives us one more equation dQ + 23 = 2X (using this equation we can calulate X = -1. so we can find d. SUFFICIENT St.2 Gives another similar equation . Sufficient. I...

Even I thought C, but ans was B, I did not understand,
Since the question does not say anything on positive and negative numbers,(we get two different answers when we consider -ve odd consecutive and all +ve odd consecutives,) I think the question is wrong in magoosh, or my solution is wrong.

consecutive odd (magoosh - very hard)
Set K consists of a finite number of consecutive odd integers. If x is the smallest number in K and y is the greatest, then y - x =
(1) The average (arithmetic mean) of set K is –36.
(2) There are 8 numbers in set K.

is M > N, we are given m and n are positive consecutive integers. st 1. m-1 and n+1 are consecutive, this can only be true if m is > than n we have to take the statements as true and need to prove it. Only way m-1 and n+1 are consecutive is example : m = 4 and n = 3, m-1 = 4-1 =3 n+1= 3+1 = 4 proved...

geometry-triangles
Is a Triangle ABC Isosceles Triangle.
1. BD=BC
2. Area of ABD and ACD are same.
(I saw this question in Magoosh GMAT, Ans is D, but my question is for an equilateral traingle also BD=BC. How can statement 1 is sufficient)
