Question

Select the set in which the numbers are related in the same way as are the numbers of the following sets.
(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – Operations on 13 such as adding/subtracting/multiplying to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
(43, 48, 5)
(49, 70, 21)​

A.

(36, 52, 13)

B.

(45, 52, 4)

C.

(20, 34, 14)

D.

(48, 71, 20)

Correct option is C

Given sets:
(43, 48, 5)
(49, 70, 21)​
Logic:  First + Third = Second
(43, 48, 5)
Check:
43 + 5 = 48
(49, 70, 21)
Check:
49 + 21 = 70
Now, let's check the options:
A) (36, 52, 13)
36 + 13 = 49 ≠ 52
B) (45, 52, 4)
45 + 4 = 49 ≠ 52
C) (20, 34, 14)
20 + 14 = 34 (Follow)
D) (48, 71, 20)
48 + 20 = 68 ≠ 71
Thus, correct option is (c).
