If 16 $ 8 = 512 and 45 $ 28 = 5040, then what is the value of 51 $ 27?
Show answer & explanation
Correct answer: D
Explanation
Just as
16 $ 8 = 512
16 × 8 × 4 = 512
And
45 $ 28 = 5040
45 × 28 × 4 = 5040
both equations are multiplied by 4.
Similarly,
51 $ 27
51 × 27 × 4
= 1377 × 4
= 5508
Correct answer: 5508
