यदि \(x\in\mathbb{N}\) और (3x+2<20) है तो हल समुच्चय कौन सा है?
If \(x\in\mathbb{N}\) and (3x+2<20), what is the solution set?
Explanation opens after your attempt
Correct Answer
A. ({1,2,3,4,5})
Concept
The inequality gives (3x<18), so (x<6). In \(\mathbb{N}\), usually take positive integers starting from (1).
Why this answer is correct
The correct answer is A. ({1,2,3,4,5}). The inequality gives (3x<18), so (x<6). In \(\mathbb{N}\), usually take positive integers starting from (1).
Exam Tip
असमता से (3x<18) इसलिए (x<6) है। \(\mathbb{N}\) में सामान्यतः (1) से शुरू होने वाले धनात्मक पूर्णांक लें।
