Ans. A
The numbers are squared in ascending order
In first circle,
(3)2 = 9
(4)2 = 16
(5)2 = 25
(6)2 = 36.
In second circle,
(4)2 = 16
(5)2 = 25
(6)2 = 36
(7)2 = 49.
In third circle,
(6)2 = 36
(7)2 = 49
(8)2 = 64
(9)2 = 81.
Q.2 Find the minimum number of straight lines required to make the given figure.
A)13
B)15
C)17
D)19
Ans. A
The figure may be labelled as shown.
