Find the missing number having the same relationship as between the numbers on the left side two numbers:
125 : 120 :: 343 : ?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 336
125 is the cube of 5, and 120 is \(5^3-5\).
\(125=5^3\), and \(5^3-5=120\)
\(343=7^3\), so the missing number is \(7^3-7=336\)
