Question

Q.172. Select the set in which the numbers are related in the same way as are the numbers of the following sets \[ (30,14,8) \quad(84,12,36) \]

1. (108, 18, 45)
2. (68, 14, 49)
3. (21, 28, 11)
4. (24, 8, 10)

Answer 1

For the first set,

30 - 14 = 16

16 ÷ 2 = 8

Similarly, for the second set,

Now, for the second set,

84 - 12 = 72

72 ÷ 2 = 36

In the same way, we need to follow the steps in the options:

In option 1, 

108 - 18 = 90

90 ÷ 2 = 45

Thus, option 1 is correct.
