Correct answer: A. 16

Explanation

Read literally, 'C = subtracted from' means a C b = b - a. Do the division and multiplication first: 8 A 2 D 6 = 8 / 2 x 6 = 24. Then 20 C 12 = 12 - 20 = -8, and -8 B 24 means -8 added to 24 = 16. The official key is 16. (If C is read as plain minus, 20 - 12 + 24 = 32.) Hence the answer is 16.शब्दशः 'C = घटाने को' का अर्थ है a C b = b - a। पहले भाग और गुणा करें: 8 A 2 D 6 = 8 / 2 x 6 = 24। फिर 20 C 12 = 12 - 20 = -8 और -8 B 24 अर्थात 24 में -8 जोड़ना = 16। आधिकारिक कुंजी 16 है। (यदि C को सामान्य घटाव मानें तो 20 - 12 + 24 = 32 आता है।) अतः उत्तर 16 है।
