Find the missing number: \(11 : 1452 :: 12 : ?\)
1872
Find how the first number 11 generates 1452.
Notice that \(11^2 = 121\) and \(121 \times 12 = 1452\). So the rule is \(n^2 \times (n+1)\), i.e. the number squared, multiplied by the next number.
Apply the same rule to 12: \(12^2 = 144\), and \(144 \times 13 = 1872\).
Hence, the missing number is 1872.

Select the option that is related to the third number in the same way as the second number is related to the first number.
12 : 60 :: 16 : ?
Select the option that is related to the third number in the same way as the second number is related to the first number.
16 : 144 :: 28 : ?
Select the set in which the numbers are related in the same way as are the numbers of the following sets.
(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13 - Operations on 13 such as adding / subtracting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed)
