Correct Answer: 11 : 47
Solution :
Given:
7 : 31
Multiply the first number by 4 and then add 3 to it, to get the second number in each pair –
7 : 31→(7 × 4) + 3 = 28 + 3 = 31
Let's check the options –
First option:
11 : 37→(11 × 4) + 3 = 44 + 3 = 47
≠ 37
Second option:
11 : 28→(11 × 4) + 3 = 44 + 3 = 47
≠ 28
Third option:
11 : 47→(11 × 4) + 3 = 44 + 3 = 47
Fourth option:
11 : 12→(11 × 4) + 3 = 44 + 3 = 47
≠ 12
So, only the third option follows the same pattern as the given number pair. Hence, the third option is correct.
