Question

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.) (20, 76, 91) (87, 41, 123)

• A. (57, 18, 100)
• B. (84, 47, 126)
• C. (40, 80, 15)
• D. (47, 19, 51)

Answer 1

Answer:

B. (84, 47, 126)

Check the relation:

First set

(20, 76, 91)
20 + 76 - 5 = 91

Second set

(87, 41, 123)
87 + 41 - 5 = 123

So the pattern is:

a+b-5=c

Check the pattern:

Given relation:

a+b-5=c

Now test ((84, 47, 126)):

84 + 47 - 5 = 131 - 5 = 126

The set (84, 47, 126) follows the same relation.
