If ‘A’ stands for ‘÷’, ‘B’ stands for ‘×’, ‘C’ stands for ‘+’ and ‘D’ stands for ‘−’, what will come in place of the question mark (?) in the following equation?
50 D 100 C 17 B 300 A 100 = ?

Correct option is B

Given:50 D 100 C 17 B 300 A 100 = ?
Symbols are coded as:
A = ÷
B = ×
C = +
D = −
Equation to solve:
50 − 100 + 17 × 300 ÷ 100 = ?
Logic:
Replace each coded letter with its mathematical operation and follow BODMAS (Brackets, Orders, Division/Multiplication, Addition/Subtraction) rule.
Explanation:
Step 1: Replace symbols:
50 − 100 + 17 × 300 ÷ 100
Step 2: Perform multiplication and division first from left to right:
17 × 300 = 5100
5100 ÷ 100 = 51
Step 3: Now equation becomes:
50 − 100 + 51
Step 4: Perform addition and subtraction from left to right:
50 − 100 = −50
(−50) + 51 = 1
Final Answer: 1
S. Ans. (b)
