Question:
If 512 @ 20 # 10 = 522 and 620 @ 40 # 20 = 640, then find 410 @ 30 # 15 = ?
यदि 512 @ 20 # 10 = 522 और 620 @ 40 # 20 = 640 है, तो 410 @ 30 # 15 = ? का मान ज्ञात कीजिए।
Options:
- 425
- 430
- 435
- 440
- 425
- 430
- 435
- 440
Correct Answer: a)
Explanation:
The operations are: ‘@’ means ‘+’ and ‘#’ means ‘-‘:
\(512 + 20 – 10 = 522\)
\(620 + 40 – 20 = 640\)
\(410 + 30 – 15 = 425\).
संक्रिया: ‘@’ का अर्थ ‘+’ और ‘#’ का अर्थ ‘-‘ है:
\(410 + 30 – 15 = 425\)।
