Question

If 5 # 3 @ 3 = 12 and 7 # 2 @ 4 = 10, then what will be 2 # 9 @ 5?

• A. 26
• B. 32
• C. 13
• D. 29

Answer 1

Answer:

C. 13

The pattern followed is,

For 5 # 3 @ 3 = 12,

$5\times{3}-3=15-3=12$

And

For 7 # 2 @ 4 = 10

7 $\times$ 2 – 4 = 14 – 4 = 10

Similarly,

For 2 # 9 @ 5

2 × 9 – 5 = 18 – 5 = 13

Hence the answer is 13.

Hence, “13” is the correct answer.
