If 569 & 4 $ 14 = 513 and 718 & 47 $ 38 = -1068, then what is the value of 890 & 5 $ 5?
Show answer & explanation
Correct answer: B
Explanation
Just as
569 & 4 × 14 = 513
& = − (subtraction)
$ = × (multiplication)
569−(4 × 14)
569−56=513
And
718 & 47 × 38 = -1068
718−(47 × 38)
47 × 38=1786
718−1786=−1068
Similarly
890 & 5 × 5
890−(5 × 5)
890−25=865
Correct answer = 865
