Question : Directions: Study the given pattern carefully and select the number that can replace the question mark (?) in it.
Option 1: 154
Option 2: 150
Option 3: 165
Option 4: 157
Correct Answer: 157
Solution : Multiply the number given in column one by 3 and add 1 to the resultant to get the second column and multiply the first column by 9 and add 4 to the resultant to get the third column –
In the first row→(9 × 3) + 1 = 28; (9 × 9) + 4 = 85
In the third row→(7 × 3) + 1 = 22; (7 × 9) + 4 = 67
Similarly, follow the same pattern in the second row→(17 × 3) + 1 = 52; (17 × 9) + 4 = 157
So, the required number is 157. Hence, the fourth option is correct.
