Question

Find out the set among the four sets which is like the given set

(13 ∶ 20 ∶ 27)

1. (3 ∶ 11 ∶ 18)
2. (18 ∶ 25 ∶ 32)
3. (18 ∶ 27 ∶ 72)
4. (7 ∶ 14 ∶ 28)

Answer 1

Correct Answer - Option 2 : (18 ∶ 25 ∶ 32)

The Logic here is as follows :

(13 : 20 : 27)

13 + 7 = 20

20 + 7 = 27

Option 1: (3 : 11 : 18)

3 + 7 = 10 ≠ 11

11 + 7 = 18 

Option 2: (18 : 25 : 32)

18 + 7 = 25

25 + 7 = 32

Option 3: (18 : 27 : 72)

18 + 7 = 25 ≠ 27

27 + 7 = 34 ≠ 72

Option 4: (7 : 14 : 28)

7 + 7 = 14

14 + 7 = 21 ≠ 28

Hence, the correct answer is (18 : 25 : 32) .
