If 'A' means '÷', 'B' means 'x', 'C' means '+' and 'D' means '−', then what will come in place of the question mark (?) in the following equation?
(80 A 8) B 5 C 14 B 2 D 11 B 3 C 72 A4 = ?
Information Given:
A = ÷
B = ×
C = +
D = −
Expression:
(80 A 8) B 5 C 14 B 2 D 11 B 3 C 72 A 4
Logic:
Replace symbols with operators and solve using BODMAS rule.
Explanation:
Logic: Substitute operators then compute stepwise.
(80 ÷ 8) × 5 + 14 × 2 − 11 × 3 + 72 ÷ 4
80 ÷ 8 = 10
72 ÷ 4 = 18
10 × 5 + 14 × 2 − 11 × 3 + 18
= 50 + 28 − 33 + 18
= 78 − 33 + 18
= 45 + 18
= 63
Final Answer:
63
Final Correct Option:
A
