Correct option is A
Given:
Symbols defined as follows:
A refers to addition (+)
B refers to subtraction (−)
C refers to division (÷)
Equations Provided:
15A8B9C3=20
15+8-9÷3=20
15+8-3=20
23-3=20
20 = 20
and
18A20B15C5=35
18+20-15÷5=35
18+20-3=35
38-3=35
35 = 35
Similarly,
8 A 6 B 4 C 2 =?
= 8 + 6 - 4 ÷ 2
= 8 + 6 - 2
= 14 - 2
= 12
Correct answer is (a) 12.
