Infosys Company Numerical Ability Age Problem

I bought a car with a peculiar 5 digit numbered licence plate which on reversing could still be read. On reversing value is increased by 78633.Whats the original number if all digits were different?

Read Solution (Total 5)

answer is 10968.
89601
10968
------
78633
------

i)we can't read 2,3,4,5,7 while they are reversed.
ii)so that number is built with 1,6,8,9,0.
iii) difference between both numbers is 78633.
iv) and all digits are different

Only 0 1 6 8 and 9 can be read upside down. So on rearranging these digits we get the answer as 10968.

Infosys Other Question

There are 6 volumes of books on a rack kept in order ( ie vol.1, vol. 2 and so on ). Give the position after the following changes were noticed. All books have been changed Vol.5 was directly to the right of Vol.2 Vol.4 has Vol.6 to its left and both weren't at Vol.3's place.Vol.1 has Vol.3 on right and Vol.5 on left. An even numbered volume is at Vol.5's place Find the order in which the books are kept now. There are two balls touching each other circumferentially. The radius of the big ball is 4 times the diameter of the small all. The outer small ball rotates in anticlockwise direction circumferentially over the bigger one at the rate of 16 rev/sec. The bigger wheel also rotates anticlockwise at N rev/sec. What is 'N' for the horizontal line from the centre of small wheel always is horizontal.
