Question : Directions: Select the option that is related to the third number in the same way as the second number is related to the first number.
64 : 15 :: 88 : ?
Option 1: 21
Option 2: 7
Option 3: 12
Option 4: 31
Correct Answer: 21
Solution :
Given:
64 : 15 :: 88 : ?
Subtract 4 from the first number, then divide the resultant by 4, to get the second number in each number pair
Like, 64 : 15→64 – 4 = 60; 60 ÷ 4 = 15
Similarly, follow the same pattern for 88 : ?→88 – 4 = 84; 84 ÷ 4 = 21
So, 88 is related to 21. Hence, the first option is correct.
