Find the missing term:
Answer
Correct Answer : a ) 7
Explanation :
The logic in the above table is column-wise.
The common logic in all the three columns is:
Term in row 3 = [(Term in row 1)2 × Term in row 2] – 50
Thus, considering the Ist column
[(5)2 × 10] – 50 = 250 – 50 = 200 (Term in row 3)
Considering IInd column
[(11)2 × 3] – 50 = 363 – 50 = 313 (Term in row 3)
Considering IIIrd column
[(?)2 × 5] – 50 = 195 (Term in row 3)
[(?)2 × 5 = 245
(?)2 = 49
? = 7
Hence, (a) is the correct answer.
