Three times a number (n) is not less than (18). Which inequality is correct?एक संख्या (n) का तीन गुना (18) से कम नहीं है। सही असमानता कौन सी है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (3n\geq 18)(3n\geq 18)
Not less than means greater than or equal to, so (3n\geq 18). Pay attention to negative phrases while translating words into symbols.कम नहीं का अर्थ उससे बड़ा या बराबर है इसलिए (3n\geq 18)। वाक्य को प्रतीकों में बदलते समय नकारात्मक शब्दों पर ध्यान दें।
