If 40 A 10 B 8 C 15 = 65 and (15 A 30) B 9 C 20 = 70 , then 7 A 9 B 3 C 8 = ?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 29.
From 40 A 10 B 8 C 15 = 65, we get
⇒ (40 × 10 ÷ 8) + 15 = 65
⇒ 50 + 15 = 65
⇒ 65 = 65
From 15 A 30 B 9 C 20 = 70, we get
⇒ (15 × 30) ÷ 9 + 20 = 70
⇒ 50 + 20 = 70
⇒ 70 = 70
Similarly for 7 A 9 B 3 C 8 = ?, we get
⇒ (7 × 9 ÷ 3) + 8 = ?
⇒ 21 + 8
⇒ 29
