1. The citizens of planet nigiet are 8 fingered and have thus developed their decimal system in base 8. A certain street in nigiet contains 1000 (in base 8 buildings numbered 1 to 1000. How many 3s are used in numbering these buildings? The citizens of planet nigiet are 8 fingered and have thus developed their decimal system in base 8.

300 in the nigiets base 8
192 in the base 10 for us ....
the answer is total of 192 (base 10)

if mod(99919,i) = 0 then
4. Cube has colors blue, red ,yellow each on two opposite sides. cube is divided into "32 small cubes and 4 large cubes". question: how many cubes (on 36 cubes) have blue at least one side. how many cubes have colors on two sides?
If you paint the cube such that:
Blue and Blue are on opposite sides
Red and Red are on opposite side
Yellow and Yellow are on opposite side
And, since the question didnt state where the 32 smaller could be, Im placing the 32 smaller cubes on the sides with Blue paint. Thus:
32 cubes have Blue on at least one side.
20 cubes have have colors on two sides.
5. A, B, C, D went to a hotel and planned to share the bill equally. But afterwards they changed their plan and to pay proportional to consumption A paid 240, B & C paid equally, D paid only half the amount that he should have paid based on the first plan. What is the amount paid by B?
jus suppose 1st plan all paid x rs means individually x/4
x eqals= 240+x/4+x/4+x/8
solving x equals 640
paid by B is x/4
6. There is a 20 X 20 array. In Each row, the shortest person is called and among them, the tallest person is A. In Each column, the shortest person is called and among them, the tallest person is B. Who is taller?
A is taller
Let velocity of A,B and C be a,b,c resp.
2(pi)r/88 = a+c
2(pi)r/110 = b+c
we have to find 2(pi)r/a-b
Given that there are 8 Prime Numbers under 20, and if the limit is only random numbers under 20 then there is a 40% chance of getting a prime number.
