Question

Calculate the value of X + Y

• A. X + Y = 67
• B. X + Y = 76
• C. X + Y = 87
• D. X + Y = 78

Answer 1

The correct option is D X + Y = 78

To find the value of X, we look at the pattern followed by values of A.


$\therefore X=9+4=13$

Now, to find the value of Y, we relate the values of A to the corresponding values of B.


$\therefore Y=13\times 5=65$

$\text{Hence,}X+Y=13+65=78$
