एक कर्मचारी के वेतन में 20% की कटौती की जाती है। वह वेतन में 20% की वृद्धि प्राप्त करके अपना मूल वेतन पुनः प्राप्त कर सकता है।
Detailed Solution & Logic
78% of all students/ 78 % सभी छात्रों का
Let total students = 100
Fail in Maths = 19
Fail in English = 10
Fail in both = 7
Students failing in at least one subject:
$19 + 10 - 7 = 22$
So, students passing in both subjects:
$100 - 22 = 78$
✅ Final Answer: 78% of all students
Correct option: 78%
