share plz....
see bro, 24k^2 + 201 needs to be written in terms of 2k +3.. so i took it as 6 ( 2k+3)(2k-3) +255..
now as 2k+3 is a divisor of the first term in the summation, it must also divide 255..
now, 255 = 3X 5 X 17
num of factors of 255= (1+1)(1+1)(1+1) = 8
ie 1,3, 5, 15,17, 51,....255
among thses, 1 and 3 wont satisfy the 2k+3 condition..so 6 numbers..
hope, this is right

I suggest that / he goes / to the doctor as soon as he returns from taking the examination/NE

lost it somewhere in between but nice answer

@mr.seven
i just take sides 1, 1,rt2 so 2p=2+rt2 area =1/2=2p/4+2rt2
2nd one A.P>=G.P
SO ANS IS RT8P check question again i think may be some type error in place of p
3rd 3.just find x,y-intercepts then use area of quadrilateral 1/2{(x1-x3)(y2-y4)-(x2-x4)(y1-y3)}
bhai 1st wala plz explain again

bhai, I am not sure whether its the correct one.. that was how I solved it.. and its highly exposed to calculation errors

plz share what z b d replacement..

share approach plz..
yar squared : (2k+3)= 4k^2 + 9+ 12K

so no i made above = 24K^2 + 54 + 147
nw = 6(4K^2 + 9 + 12K) + 147 - 72K

divided: so (147-72K)/ (2k+3) shld b intg

soo found 2 values marked 4 :P

is it correct?

dude if u wanted to put values nly then u cu have put it n orignal one.....why to solve like thz?....No offense , just asking...
answer is 6..........so 6 value will satisfy thz equation
332
@JS-M said: I suggest that / he goes / to the doctor as soon as he returns from taking the examination/NE

In B, it should be he pay a visit.. and also in C, i think we cant return from taking an examination.. may be it is " returns from the examination ".. not sure bout both the said cases..
333
@JS-M said: I suggest that / he goes / to the doctor as soon as he returns from taking the examination/NE
my take 3rd part i.e there should be "after taking" or "after giving"
someone plz correct me if i am wrong
