Select the option in which the numbers share the same relationship as that shared by the given pair of numbers. 48 : 42

A63 : 28

B65: 28

C69 : 32

D48: 24

Answer:

A. 63 : 28

Read Explanation:

The correct option is 63 : 28.

Why 63 : 28 is the Correct Choice

the logic followed by the pair 48 : 42 is:
(Product of the digits of the 1st number)+10=2nd number\mathbf{(\text{Product of the digits of the 1st number}) + 10 = \text{2nd number}}

Applying this rule to 63 : 28:

  1. Multiply the digits of the first number (63):
    6×3=186 \times 3 = 18

  2. Add 10 to the result:
    18+10=2818 + 10 = \mathbf{28}


Why the Other Options are Incorrect

  • 65 : 28 (6×5)+10=30+10=40\rightarrow (6 \times 5) + 10 = 30 + 10 = 40 (Not equal to 28)

  • 69 : 32 (6×9)+10=54+10=64\rightarrow (6 \times 9) + 10 = 54 + 10 = 64 (Not equal to 32)

  • 48 : 24 (4×8)+10=32+10=42\rightarrow (4 \times 8) + 10 = 32 + 10 = 42 (Not equal to 24)
