Hey u all puys,plz solve this ques as it makes a lot of puzzle 2 me....

Q:-the no of terms in an AP is odd.if the sum of all terms is 45 and the no of terms is 4 more than tha middle term,find the middle term-

1.9

2.4

3.6

4.5

answer is 5

(n-1)*Middle Term = 45- Middle Term

so, Middle term = 45/n

now n=Middle term(m) +4

i.e. m(m+4) = 45

5(5+4) = 45

hence m = 5

> x - 7xy + 12y - 4 = 0
D should be a perfect sq
49y - 48y + 16 should be a perfect sq
y + 16 = p
(p - y)(p + y) = 16 = 2*8
p = 5, y = 3
So, only one possible value.
Hi chill Bhai,
I got your solution man however can you pls explain why D should have to be a perfect sq ...

x - 7xy + 12y - 4 = 0

D should be a perfect sq

49y - 48y + 16 should be a perfect sq

y + 16 = p

(p - y)(p + y) = 16 = 2*8

p = 5, y = 3

So, only one possible value.

Is it 6
Sorry. That's incorrect.

(x+y)=k(x-y)

=> (x+y)^2 = k(x-y)(x+y)

=> x^2+y^2+2xy = k(x^2-y^2)

=> x^2+y^2 = k(x^2-y^2)-2xy

Is it none of the above.

geometric approach :

(x+y) = k(x-y)

here, x+y is line 1 and x-y is line 2.

These who are equated hence they have same distance from the origion.

slope of line 1 : 1/1 = 1

slope of line 2 : -1/1 = -1

slope1*slope2 = -1

hence these two lines are perpendicular.

x^2+y^2 is the perpendicular distance from and of these two lines which is neither dependent om x^2-y^2 and xy.

so, Is it none of the above.
