यदि (p) परिमेय है और (q) अपरिमेय है, तो (q-p) कैसी संख्या होगी?
If (p) is rational and (q) is irrational, what type of number is (q-p)?
Explanation opens after your attempt
Correct Answer
B. हमेशा अपरिमेयAlways irrational
Concept
Subtracting a rational number from an irrational number leaves an irrational part.
Why this answer is correct
If the result were rational, then (q=(q-p)+p) would be rational, which is impossible.
Exam Tip
Remember the rules for addition and subtraction of rational and irrational numbers. चरण 1: अपरिमेय संख्या में से परिमेय संख्या घटाने पर अपरिमेय भाग बचता है। चरण 2: यदि परिणाम परिमेय हो, तो (q=(q-p)+p) परिमेय हो जाएगा, जो गलत है। चरण 3: परिमेय और अपरिमेय के जोड़-घटाव के नियम याद रखें।
