If 15 A 8 B 9 C 3 = 20 and 18 A 20 B 15 C 5 = 35, then 8 A 6 B 4 C 2 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 12.
The logic followed is:
A is coded as '+', B is coded as '-', C is coded as '÷'.
15 A 8 B 9 C 3 = 20
⇒ 15 + 8 - 9 ÷ 3 = 20
⇒ 15 + 8 - 3 = 20
⇒ 23 - 3 = 20
⇒ 20 = 20
18 A 20 B 15 C 5 = 35
⇒ 18 + 20 - 15 ÷ 5 = 35
⇒ 18 + 20 - 3 = 35
⇒ 38 - 3 = 35
⇒ 35 = 35
Similarly,
8 A 6 B 4 C 2 = ?
⇒ 8 + 6 - 4 ÷ 2 = ?
⇒ 8 + 6 - 2 = ?
⇒ 14 - 2 = ?
⇒ 12 = ?
