In the following question, select the number/symbol that will replace the question mark (?) to complete the analogy: 90 : __?___ :: 72 : 240
272
Write each number as a product of consecutive numbers: 72 = 9 × 8 and 240 = 16 × 15.
The second pair is formed by adding 7 to both factors: 9 + 7 = 16 and 8 + 7 = 15.
90 = 10 × 9, so the missing number = (10 + 7) × (9 + 7)
= 17 × 16
= 272
Hence, 272.
