The given table represents the production of different types of motorcycles (in thousands) over a period of six years. Study the table carefully and answer the questions that follows: दी गयी तालिका छः वर्षों की अवधि के दौरान अलग-अलग प्रकार की मोटर साइकिलों के उत्पादन ( हज़ार में ) को दर्शाती है | इस तालिका का ध्यानपूर्वक अध्ययन करें तथा फिर पूछे गए प्रश्नों का उत्तर दीजिए | What is the ratio of the total number of motorcycles of type B produced in 2016 and 2018 to the total number of motorcycles of type D produced in 2013, 2015 and 2016? 2016 तथा 2018 में उत्पादित की गयी B प्रकार की मोटरसाइकिलों की कुल संख्या का 2013, 2015 और 2016 में उत्पादिति D प्रकार की मोटरसाइकिलों की कुल संख्या के साथ अनुपात ज्ञात कीजिए |

Prepare a frequency table of the following scores obtained by 50 students in a test: 42, 51, 21, 42, 37, 37, 42, 49, 38, 52 7, 33, 17, 44, 39, 7, 14, 27, 39, 42 42, 62, 37, 39, 67, 51, 53, 53, 59, 41 29, 38, 27, 31, 54, 19, 53, 51, 22, 61 42, 39, 59, 47, 33, 34, 16, 37, 57, 43

The number first increased by 16% and then increased by 14%. The number, so obtained, is now decreased by 30%. What is the net increase or decrease percent in the original number (nearest to an integer) ? एक संख्या पहले 16% से बढ़ा दी जाती है और फिर 14% बढ़ा दी जाती है | इस प्रकार प्राप्त संख्या को 30% कम कर दिया जाता है | मूल संख्या में शुद्ध प्रतिशत वृद्धि या कमी (निकटतम पूर्णाक तक ) ज्ञात करें |
