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 ]

3.)An artist has exactly seven paintings -- ,T,U,V,W,X,Y, and Z -- from which she must choose exactly five to be in an exhibit.         8 marks
Any combination is acceptable provided it meets the following conditions:
* If T is chosen , X cannot be chosen
* If U is chosen , Y must also be chosen
* If V is chosen , X must also be chosen

1) Which one of the following is an acceptable combination of  paintings for inclusion in the exhibit?
A. T,U,V,X,Y
B. T,U,V,Y,Z
C. T,W,X,Y,Z
D. U,V,W,Y,Z
E.  U,V,W,Z,Y
Ans E
When T is present X shud be excluded so above cases failed. When V is there X must be there so

2) If painting T is chosen to be among the paintings included in the exhibit which one of the following cannot be chosen to be among the paintings included in the exhibit?
A. U
B. V
C. W
D. Y
E. Z
Ans B
when T is there X not there, so if u include V it brings X along with it

3) Which one of the following substitutions can the artist always make without violating restrictions affecting the combination of paintings given that the painting mentioned first was not, and the painting mentioned first was not, and the painting mentioned second was, originally going to be chosen ?
A. T replaces V
B. U replaces Y
C. V replaces X
D. W replaces Y
E. Z replaces W
Ans E
There r no such conditions for Z and W, they can be selected as u want.

A. T is not chosen
B. Y is not chosen
C. U is chosen
D. W is chosen
E. Z is chosen

When V is there, X included, which contradicts T's condtn, so it must be excluded

This was the simplest

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
