Hi rainbowlife, You might have measured the markings on the numberline which are obviously same. What question is asking is the arrow pointing to a point.You will notice that arrow named E is slightly between markings 1 and 2 while the arrow named A is exactly on marking -2.

There is no rule as to why the this line segment should be greater th...

Yes..this will mostly be the case for inference questions because it would require you to make assumption like (if X causing y then Y can be caused by X) such info is not given in the argument. For inference stick to just WHAT IS SPECIFICALLY GIVEN IN THE PREMISE. GMAT does not wan't you to use your...

Hi Kaunteya, Start off by simplifying all the terms in to their primary factors and then equate the powers of exponents on both sides of equation. 27^(4x + 2) * 162^(-2x) * 36^x * 9^(6–2x) = 1 or (3)^4(4x + 2) * (2*81)^(-2x) * (6*6)^x * 3^2(6–2x) = 1 or (3)^4(4x + 2) * (2)^(-2x) * (3)^4(-2x) * (3*2)...

(15^x + 15^x+1) = 15^y4^y (15^x + 15^x+1) can be simplified to: (15^x + 15^x(15^1)) 15^x(1+15) :Almost there or 15^x(16) = 15^y4^y or 15^x(4)^2 = 15^y4^y Since both the sides are equal and both have same BASES so the powers MUST also be same. This means y = 2 Hope it helps Thanks Komal

Hi moneyman, To solve this problem lets take the each option one by one: 1 ) f(x)=x^2 f(a) = a^2 F(b)=b^2 F(a + b)=(a+b)^2 a^2 + b^2 not = (a+b)^2 INCORRECT 2) f(x)=x+1 f(a) = a+1 f(b)=b+1 f(a + b)=(a+b)+1 (a+1) +( b+1) not = (a+b +1) INCORRECT 3 ) f(x)=sq.rt x f(a) = sq.rt a f(b)=sq.rt b f(a + b)=s...

Hi Hemanth,
It would be great if you could post each question separately.
It would be easier for everyone to respond and relate.
