If 30 $ 90 % 40 = c, then the value of 5 @ c # 20

A 20 Correct Answer Incorrect Answer
B 30 Correct Answer Incorrect Answer
C 35 Correct Answer Incorrect Answer
D 38 Correct Answer Incorrect Answer
E none of these Correct Answer Incorrect Answer

Solution

: 30 $ 90 % 40 = c ⇒ 30% of 90 + 40 ⇒ 27 + 40 = 67 5 @ c # 20 ⇒ 5³ - (67 + 20) = 125 - 87 = 38
