Q.3 Consider the following diagrams:
x men, working at constant speed, do a certain job in y days. Which one of these diagrams shows the relation between x and y?

A) diagram I
B) diagram II
C) diagram III

Q.4 Consider the following matrix:

3	370	7
2	224	6
1	730	X
What is the number at 'X' in the above matrix?
A) 5
B) 8
C) 9
D) 11
Ans. C
Since, 33 + 73 = 27 + 343
=370
& 23 + 63 =8+ 216
=224
Therefore,
13+x3=730
X3=730-1
=729
X=(729)1/3
X=9
