Find the missing value that fits the same relationship as the other pairs. 6 : 108 :: ? : 54 :: 10 : 150
- 8
- 6
- 10
- 4
Correct answer: 6
Solution
In 8:96, the multiplier is 96/8 = 12. In 12:216, the multiplier is 216/12 = 18. The multiplier equals n + 4: for 8 it is 12, for 12 it is 16... actually multiplier = n+4+? Let me verify: 8x12=96, 12x18=216. Difference in multipliers is 6 for difference of 4 in n, so multiplier grows by 1.5 per unit. For n: multiplier = n + 4 gives 8+4=12 ✓. For 12: 12+6=18 ✓ (not n+4). Pattern: multiplier = n + (n/4 x 3)? Try: if n=6, multiplier = 9, 6x9=54 ✓. Answer: 6.
