Select the option that is related to the third number in the same way as the second number is related to the first number and the sixth number is related to the fifth number.
17 : 255 :: 21 : ? :: 24 : 528
- A399
- B419
- C319
- D499
Solution & Step-by-step Explanation
Let's identify the relationship pattern between the pairs of numbers:
First pair: 17:255
17×(17−2)=17×15=255
Third pair: 24:528
24×(24−2)=24×22=528
Applying the same logic to the second pair with 21:
21×(21−2)=21×19=399
First pair: 17:255
17×(17−2)=17×15=255
Third pair: 24:528
24×(24−2)=24×22=528
Applying the same logic to the second pair with 21:
21×(21−2)=21×19=399
