Question : Directions: Study the given pattern carefully and select the number that can replace the question mark (?) in it.
First row - 6, 9, 90
Second row - 12, 8, 120
Third row - 13, 6, ?
(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 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.)
Option 1: 114
Option 2: 125
Option 3: 102
Option 4: 110
Correct Answer: 114
Solution :
Given:
First row - 6, 9, 90
Second row - 12, 8, 120
Third row - 13, 6, ?
The sum of the first two numbers is multiplied by 6, to get the third number.
First row:
(6 + 9) × 6 = 15 × 6 = 90
Second row:
(12 + 8) × 6 = 20 × 6 = 120
Third row:
(13 + 6) × 6 = 19 × 6 = 114
So, 114 is the required missing number. Hence, the first option is correct.
