Cogs. Answer is C - 48 cogs.

First find the length of circumference. 2PiR = 6Pi.
Then find the quantity of Pi/16 sections.
6Pi = Pi/16x. x = 96, so number of cogs = 48 (96/2).

Hope it's clear.

Games. The answer is A - 10%.

Total number of games = 10.
Played till now 7 and we already have 2 ties.
So out of 10 games you can have 2, 3, 4 or 5 ties that gives you 20, 30, 40, 50 percent respectively.
And only 10% can no fit into this league. :)

Hope it's clear.

1) 64

2 cogs will occupy a space of 3pi/16

Hence a space of 2pi3 will be occupied by 2*2pi3/(3pi/16) = 64


2) 10%

Total number of games to be played is 10
Number of games played till now is 7

And number of games tied till now is 2

If the number of games tied remains 2. the percent is 20%.
hence it can never be 10%

Q1:

C

Each cog will occupy (Including space) = PI/8
Total cogs = 6PI/(PI/8) = 48

Q2:

A

Current games = 7
Current matches with tie = 2
Current matches with results = 5
More games to be played = 3
Total games in the end = 10

So we may have 2,3,4 or 5 tie.

So the tie can not 10%.
