Question
The three numbers in each group are related in the same way.Choose the number that completes the last group.( 12 [ 20 ] 5 )( 16 [ 36 ] 17 )( 14 [ ? ] 20 )
Solution
The relationship between the numbers in each group is that the middle number is the product of the first and the last number.
In the first group, 12 * 5 = 60, but the middle number is 20, which is 60 divided by 3.
In the second group, 16 * 17 = 272, but the middle number is 36, which is 272 divided by 7.5 (approximately).
So, in the third group, we need to find a number that, when multiplied by 14 and then divided by a certain number, gives us 20.
14 * 20 = 280.
If we divide 280 by 14, we get 20.
So, the missing number is 14.
