If 35 A 18 B 5 C 10 = 115 and 41 A 23 B 7 C 15 = 187, then 8 A 4 B 5 C 9 = ?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 19.
In the given equation: A is coded as '+', B is coded as '×' and C is coded as '-'.
35 A 18 B 5 C 10 = 115
⇒ 35 + (18 × 5) - 10 = 115
⇒ (35 + 90) - 10 = 115
⇒ 125 - 10 = 115
⇒ 115 = 115
And,
41 A 23 B 7 C 15 = 187
⇒ 41 + (23 × 7) - 15 = 187
⇒ (41 + 161) - 15 = 187
⇒ 202 - 15 = 187
⇒ 187 = 187
Similarly,
8 A 4 B 5 C 9 = ?
⇒ 8 + (4 × 5) - 9 = ?
⇒ (8 + 20) - 9 = ?
⇒ 28 - 9 = ?
⇒ 19 = ?
