10.) A number when divided by D leaves a remainder of 8 and when divided by 3D leaves a remainder of 21. What is the remainder left, when twice the number is divided by 3D?
answer is 3
as let no be n then
n/D=p1+8/D...........1
n/3D=p2+21/D.........2
subtract 2 from 1 it will be
2n/3D=p1-p2+3/3D so rem is 3

14. they will aske u question on time and clock
like on another planet there is day of 36 hr instead of 24 and 1 hr=90 min....and clock make two round in a day means 18 hr day and 18 hr night..so difference in hr hand and min hand ....
solution:
convet time like 12:40 to hr completely as 12+40/90

and proceed as hr hand makes 360 degree in 18 hr then in 12+40/90 how many degrees

also in 90 min minutes hand makes 360 degrees so in 40 min how many degrees ....
now subtarct both degrees found smallewer one from bigger that is answer......

they repaet question also......

15. if point set type question i.e set of points separated from a line then answer would be always no of points as we acn plot infinite points on circle each having its distinct tangent...seaparating it from other points
