Explanation:
Given, Monthly income of A = Rs. 20000 His house rent amount = 20000 × 70/100 = 14000 He spend on food = 20000 × 10/100 = 2000 Percentage savings = 100 - 70 - 10 = 20% His savings = 20000 × 20/100 = 4000 Given, Salary is increased by 15%. New salary of A = 20000 + 20000 × 15/100 = 23000 House rent amount he spent remains the same as it was earlier which is Rs. 14000. Due to the medical problem he used to spend 5% less money on food. Amount he spend on food = 2000 - 2000 × 5/100 = 1900 Total amount he spend on rent and food = 14000 + 1900 = 15900 His savings = 23000 - 15900 = 7100 Percentage change in savings = × 100 = 77.5 ∴ Percentage change in savings of A is 77.5%.
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।
