Two vertical poles 2 metres and 8 metres high stand apart on a horizontal plane . the height in metres of the point of intersection of the lines joining the top of each pole to the bottom of the other pole is.
1. 5.6
2. 1.6
3. 1.8

Read Solution (Total 3)

Here we have to apply working backworld from the option..

first optio 1
not possible the answer will be less then 2

option 2
Ratio of height of poles is 2:8=1:4
Now 1.6 is how much percentage of both poles height...

1st pole : 1.6/2*100=80%
2nd pole : 1.6/8*100=20%

ratio is 20:80=1:4

Hence the answer will be 1.6

You can apply same for option 3 if you want.

Correct me if I am wrong.

TCS Other Question

A semicircle is drawn with AB as its diameter . From c, a point on AB, a line perpendicular to AB is drawn , meeting the circumference of the semicircle at D. Given that AC=2 cm, CD= 6cm, the are of the semicircle ( in sq. cm ) will be:
1. 82pi
2. 50pi
3. 31pi
4. 55pi In this question A^B means A raised to the power B. Let f(X)=1+X+X^2+.....X^6.
The reamainder when f(X^7) is divided by f(X) is:
1. 7
2. 0
3. 6
