Explanation:
Given: The present ages of a mother and her son are in the ratio of 6 : 1 When the son becomes as old as his mother now, then the ratio of his father's age to his mother's age is 13 : 11 When the son becomes as old as his father now, then the sum of the ages of the father and son will be 115 years Calculation: Let the present age of mother and son be 6x and x and father's age be y Now, According to the question, After 5x years Mother = 6x + 5x = 11x Father = y + 5x Now y + 5x/11x = 13/11 ⇒ y = 8x So, the father's age is 8x years Again, After 7x years Father = 8x + 7x = 15x Son = x + 7x = 8x 15x + 8x = 115 years 23x = 115 years x = 115/23 = 5 years So the age of the father is 8 × 5 = 40 years ∴ The present age of the father is 40 years
বাংলা সাহিত্য ও ব্যাকরণ হলো বাংলা ভাষার দুটি অবিচ্ছেদ্য অঙ্গ। বাংলা সাহিত্য হলো বাংলা ভাষায় রচিত কবিতা, উপন্যাস, নাটক, গল্পসহ সৃজনশীল ও মননশীল রচনার সমষ্টি, যার সূচনা দশম শতাব্দীতে 'চর্যাপদ' এর মাধ্যমে। অন্যদিকে, বাংলা ব্যাকরণ হলো এমন একটি শাস্ত্র বা বিজ্ঞান, যা বাংলা ভাষার গঠন, প্রকৃতি, ধ্বনি, শব্দ ও বাক্যের নিয়ম-কানুন বিশ্লেষণ করে ভাষার শুদ্ধ রূপ ও প্রয়োগ শেখায়।
