If 28 A 49 B 77 C 11= -14 and 30 A 50 B 88 C 22 = -16, then 85 A 15 B 40 C 8 = ?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 75.
28 A 49 B 77 C 11 = -14
28 - 49 + 77 ÷ 11 = -14
⇒ 28 - 49 + 7
⇒ 35 - 49 = -14
30 A 50 B 88 C 22 = -16,
30 - 50 + 88 ÷ 22 = -16
⇒ 30 - 50 + 4
⇒ 34 - 50 = -16
Then 85 A 15 B 40 C 8 = ?
85 - 15 + 40 ÷ 8
⇒ 85 - 15 + 5
⇒ 90 - 15 = 75
