Question

Find the missing term in the given figures.

?	13	49
9	17	69
13	11	59

• A. $5$
• B. $9$
• C. $10$
• D. $21$

Answer 1

The correct option is A $5$

In the second row. 2 x 9 + 3 x 17 = 18 + 51 = 69.
In the third row, 2 X 13 + 3 x 11 = 26 + 33 = 59
Now, let the missing number in the first row be x.
Then, 2x + 3 x 13 = 49
or, 2x = 10
or, x = 5
Hence, option (A) is the correct answer.
