Answer

Answer 1)

1/3 x (54 x 150 + 60 x 300 + 36 x 450)

= 1/3 x 42300

= 14100.

Answer 2)

Required ratio of chairs = $\frac{64 x 450 + 56 x 500}{36 x 450 + 44 x 500}$

= 56800/38200

= 284/191.

Answer 3)

Required number of chairs = $\frac{3}{5} x \frac{12}{100} x 50000$
= 3600.

Q:

I am a 5 letter word.

I am normally below you. If you remove my 1st letter, you'll find me above you. If you remove my 1st & 2nd letters, you can't see me.

What am I?

Answer

Firstly, I focussed on "If you remove my 1st & 2nd letters, you can't see me". The first thing that comes to mind which we can’t see is the "AIR".

So now, what 4 letter words can be formed ending with "AIR"? Think of all the words from A to Z, considering which one lies above you. That is how we get to "HAIR".

Now, which 5 letter word can be formed ending with "HAIR"? Starting with A to Z, we reach "CHAIR" and also, it lies below us.

And the required answer is "CHAIR".
