(1/2 + 1/2^3 +1/2^5....) - 1/2 (1/2 + 1/2^3 + ...)
= 1/2(1/2 + 1/2^3 + ...)
= 1/4 + 1/4( 1/4 + 1/2^4...)
= 1/4 + 1/4( value will bw < 1)
Sum ranges between 1/4 and 1/2
Thanks

All the choices lead to real numbers. when x= 1==> sqrt(1) - (Sqrt(2) -Sqrt(1)) ==> 2 -Sqrt(2) Irrational number. But real number. Similarly for all other choices. If the number is not a real number it need to be either imaginary number or complex number. Thanks Raama

Let the no of boys be x and girls be y
8x + 7y = 2600
x and y need to be an integer.
x = 150 and y = 200.
Thanks

On a number line the points will be like this
-------- -k --------0----------k----------
For y to have maximum value x needs to be either equal to or less than -k
y is max when x<=-k
y = 2k
We need k value to find the answer for y
B is sufficient.
Thanks

Sqrt(x-3)^2 = |x-3|
|x-3| = 3-x when x-3 < 0 ie x<3
Stmt 2 says x<0
So B is sufficient.
Thanks
