🔥 ARITHMETIC 💥 1) A boat covers a certain distance downstream in 5 hours but takes 7 hours to return upstream to the starting point. If the speed of the stream is 3 km/h, then find the speed of the boat. एक नाव धारा के अनुकूल एक निश्चित दूरी को 5 घंटे में तय करती है लेकिन धारा के प्रतिकूल अपने शुरुआती बिंदु पर लौटने में 7 घंटे का समय लेती है। यदि धारा की गति 3 किमी/घंटा है, तो नाव की गति ज्ञात कीजिए। 2) Two numbers are in the ratio of 21:26. If 8 is added in each, the new numbers are in the ratio of 5:6. Find the ratio of numbers, if 4 is subtracted from each number? दो संख्याएँ 21:26 के अनुपात में हैं। यदि प्रत्येक में 8 जोड़ा जाता है, तो नई संख्याएँ 5:6 के अनुपात में होती हैं। संख्याओं का अनुपात ज्ञात कीजिए, यदि प्रत्येक संख्या में से 4 घटाया जाए? 3) A pipe can fill a rooftop water container in 12 hours and another pipe can empty 50% of the container in 10 hours. How long will it take for the empty container to be filled to 1/2 its capacity, if both the pipes are opened simultaneously? एक पाइप छत के पानी के कंटेनर को 12 घंटे में भर सकता है और दूसरा पाइप कंटेनर का 50% 10 घंटे में खाली कर सकता है। यदि दोनों पाइपों को एक साथ खोल दिया जाता है, तो खाली कंटेनर को उसकी क्षमता 1/2 तक भरने में कितना समय लगेगा? 4) A invested Rs. 4500 in a business and after some time B also joined him and invested Rs. 4800. At the end of year B received Rs. 4400 profit out of Rs. 9900. After how much time did B join the business? A ने एक व्यवसाय में 4500 रुपये का निवेश किया और कुछ समय बाद B भी उसके साथ जुड़ गया और 4800 रुपये का निवेश किया। वर्ष के अंत में B को 9900 रुपये में से 4400 रुपये का लाभ प्राप्त हुआ। B कितने समय बाद व्यवसाय में शामिल हुआ? 5) The ratio of present ages of Prakash and Sohan is 5:3. If the present age of Sohan is 27 years, then what will be the age of Prakash after 3 years? प्रकाश और सोहन की वर्तमान आयु का अनुपात 5:3 है। यदि सोहन की वर्तमान आयु 27 वर्ष है, तो 3 वर्ष बाद प्रकाश की आयु क्या होगी?
