(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

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
