The total expenses of a boarding house is partly fixed and partly varying linearly with the number of boarders.the average expense per boarder is rs 700 when there are 25 boarders and rs 600 when there are 50 boarders, what is the average expense per boarder when there are 100 boarders?a.550b.580c.540d.570please suggest.
If x 2, then which of the following is true for all real values of x and y?a) x + 2y 0 c) 2x – xy d) 2x – xy > 1 How to solve this kinda, without assuming values? Please post approach.

option C 2x-xy>0 he hoga. logic kuch anhi h values check karke he answer nikalte h

a) x + 2y one can convert the equations into lines and then regions
b) would a line passing though center .... d) rectangular hyperbola ..
well you can plot and see roughly to get to the answer. still the i would try min and max value before proceeding to graphs
@Torque024 ye he best approach h. graph wali approach aur time consuming aur complicated hogi.
@sauravd2001 Yeah, I know. It's an easy question. But the main thing is approach, values put karna would be a kinda hit and trail. So was searching ki koi logic ho.
There is a spring kept vertically fixed at one end with a ball attached to its other end.It is compressed to 60 cm from its mean position before releasing.Due to certain energy losses,every time the compression reduces by a factor of 0.75.Find the total distance traveled by the ball attached to the spring in cm. Assume for a spring (compression from mean position= expansion from mean position)
I am unnecessarily getting confused for this question"How many numbers from 1 to 700 are multiples of 2 or 3 but not 7 ?"I know that some common multiples of 2 and 3 may have to be subtracted because they appear twice in the addition. Also the number of multiples of 7 will have to be subtracted from the total number but somehow I am getting confused

multiples of 2 - 700/2 = 350 multiples of 3 - 700/3 = 233 multiples of 2 and 3 - 700/6 = 116 multiples of 2 and 7 - 700/14 = 50 multiples of 3 and 7 - 700/21 = 33 multiples of 2,3 and 7 - 700/42 = 16
