Dear Friends

I appeared for Infosys test on 24 sep 2006 held at Mumbai . the results were out on 10 oct 2006 and thankfully i was selected. Thanks to all those who have posted papers in Friends site.

I am writing the paper but questions are not in order. There were around 900 people out of which 260 cleared the apti.

English paper was same as previous paper.

1.) There is a merry-go-round race going on. One person says,"1/3 of those in front of me and 3/4 of those behind me, give the total number of children in the race". Then the number of children took part in the race? (repeated from previous papers)
Ans : 13
[ Assume there are x participants in the race.In a round race,no: of participants in front of a person wil b x-1 an that behind him wil b x-1. i.e, 1/3(x-1) + 3/4(x-1) = x ; solving x = 13 ]

A. U
B. V
C. W

4.) The temperature is noted for 5 consecutive days and it is noted that no two days have the same temperature. Moreover the product of all the 5 readings is 12. The difference is noted to the nearest degrees. What were the readings of the temperature?
Ans: -2, -1, 1, 2, 3

Factors of 12: 4*3,6*2
2*2*3 bt 2 cant b repeated so -2 and to nullify -ve sign -1 is there
so -2 *-1 * 1 * 2 *3 = 12
