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 their constituent digits. E.g. 13 – Operations on 13 such as adding / subtracting / multiplying to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.) (12, 36, 3) (15, 75, 5)
(14, 56, 4)
Look at the relation between the first and third numbers producing the middle number. For (12, 36, 3), the first number times the third gives the middle: \(12 \times 3 = 36\).
Check the second set (15, 75, 5): \(15 \times 5 = 75\). So the rule is first number times third number equals the middle number.
Test the options. (14, 56, 4): \(14 \times 4 = 56\), which matches the middle number 56.
The other options fail: \(8 \times 9 = 72 \neq 56\), \(7 \times 12 = 84 \neq 72\), \(13 \times 6 = 78 \neq 188\).
Hence, the set (14, 56, 4) follows the same relation.
