If 163 $ 448 ; 16 = 135 and 857 $ 260 ; 20 = 844, then what is the value of 686 $ 476; 17?
Show answer & explanation
Correct answer: D
Explanation
Just as
163 $ 448 ; 16 = 135
163−(448÷16)
448÷16=28
163−28=135
And
857 $ 260 ; 20 = 844
857−(260÷20)
260÷20=13
857−13=844
Similarly,
686 $ 476 ; 17
686−(476÷17)
476÷17=28
686−28=658
