If + means −, − means ×, × means ÷ and ÷ means +, then what will come in place of the question mark (?) in the following equation?
If + means −, − means ×, × means ÷ and ÷ means +, then what will come in place of the question mark (?) in the following equation?
यदि + का अर्थ −, − का अर्थ ×, × का अर्थ ÷ और ÷ का अर्थ + है, तो निम्नलिखित समीकरण में प्रश्न-चिह्न (?) के स्थान पर क्या आएगा?
51 + 8 − 8 ÷ 80 × 4 = ?
Detailed Solution & Logic
Correct Answer:
7
Given:
- means −, − means ×, × means ÷, ÷ means +
So the expression:
$51 + 8 − 8 ÷ 80 × 4$
Replace the operators:
$51 − 8 × 8 + 80 ÷ 4$
Now solve step by step (follow normal BODMAS):
First do × and ÷:
- $8 × 8 = 64$
- $80 ÷ 4 = 20$
Now expression becomes:
$51 − 64 + 20$
Compute left to right:
$51 − 64 = -13$
$-13 + 20 = 7$
Final Answer:
7
