2.A cube issue which is painted with red is cut into 27 small cubes with 6 straight cuts

a) how many cubes are there with 0 side red colour

b) how many cubes are there with one side red colour

c) how many cubes are there with two side red colour

d) how many cubes are there with three side red colour

A

0 faces coloured-1(27-(12+6+8))

1 faces coloured-6(All middle ones are one face colored red 1*6=6)

2 faces coloured-12(exclude corners other are two faces colored red so 4*3=12)

3 faces coloured-8( all corners are three faces colored red so two at front and two at back)

3.A man begins from XYZ city and drives a constant speed. After a few time he sees a milestone with 2 digits written on it.after he drives for an hour, he sees a different milestone with the identical digits, but in reversed order. After a different hour ofjourney, he sees a different milestone with original digits but with a zero ranging from them.Find the speed of the car?

A let the distance showed on 1st milestone be 10x+y distance showed on 2nd milestone be 10y+x now hit and trial let x=1 y=6 so 16 ,61,106 distance is 45km/hr. this is the only condition satisfies 4.A five digit no whose 3rd digit is 1 greater than the sum of the 1st 2 digits and the 3rd digit is double the 4th digit and 4th digit is double the 5th digit and 2nd digit is greater than 1st digit by 5. and if we multiply 4th and 5th digith we get 3rd digit. A Let the digits be denoted by p1p2p3p4p5 p3=p1+p2+1 p3=2p4 p4=2p5 p2=p1+5 hit and trial 16842 5. There was a cycle race going on. 1/5th of the those in front of a person and 5/6th of those behind him provide the totalnumber of participants. How many people took part in the race? A. Let total number of people be x 1/5(x-1)+5/6(x-1)=x so x=31 6. .B and C initially speak English but when D joined Spanish they too took up Spanish.
