If 13 A 14 B 15 C 20 = 243 and 15 A 10 B 8 C 9 = 104, then 45 A 10 B 18 C 50 = ?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 275.
A and C means '+', B means '×'
13 A 14 B 15 C 20 = 243
⇒ 13 + 14 × 15 + 20 = 243 ⇒ 13 + 210 + 20 = 243 ⇒ 243 = 243
15 A 10 B 8 C 9 = 104,
⇒ 15 + 10 × 8 + 9 = 104 ⇒ 15 + 80 + 9 = 104 ⇒ 104 = 104
Then 45 A 10 B 18 C 50 = ?
⇒ 45 + 10 × 18 + 50 = ? ⇒ 45 + 180 + 50 = ? ⇒ 275
