the number of sheet of paper available for making notebooks in 25000 each sheet make 12 pages of the notebooks each cotains 300 pages how many notebooks can be made from the paper available |
|
Answer» Step-by-step EXPLANATION: No. of Pages made by each SHEET = 12 Pages. No. of Sheets = 25000. Therefore Pages made by 25000 Sheets = 25000 x 12 = 300000 Pages. Now 300 Pages are in 1 Notebook. => 1 Page will be in 1/300 Notebook => 300000 Pages will be in (1/300)x300000 = 1000 Notebooks Hence 1000 Notebooks can be made from the paper available. |

यदि A, B और C किसी काम को 2, 4 ,8 दिन मैं करे तो तीनों मिलकर कितने दिन मै करेंगे |
|
Answer» Answer: no need; Step-by-step explanation: as they have done the work ALREADY, then why would they do the same work again? but if we think mathematically, then it would take approx three DAYS because A is the fastest and B is a little slow so if both do the work, then B would do the work HALF while A would complete the whole work hence 3 days. C not included because it takes too long, but till then the work would already have been COMPLETED. |

the number between 10 and 100 is five times the sum of its digits. if 9 be added to it the digits are reversed find the number. |
|
Answer» Step-by-step explanation: Let the number be 10 x + y sum of its numbers = x+ y according to the sum 10 x + y = 5(x + y) 10 x + y = 5 x + 5 y 10 x - 5 x = 5 y - y 5 x - 4 y = 0 if 9 is added the digits are reversed ⇒ 10 x + y + 9 = 10 y + x 10 x - x + 9 = 10 y - y 9 x - 9 y = - 9 x - y = - 1 simultaneous equation 5 x - 4 y = 0 x - y = -1 1(5 x - 4 y = 0) 5(x - y = -1) 5 x - 4 y = 0 →a 5 x - 5 y = -5→b On subtracting b from a 5 x - 4 y = 0 - 5 x + 5 y = 5 y = 5
On substituting y = 5 in x - y = - 1 we get x = 4 The number is 10 x + y = 10(4) + 5 = 45 |

परवीन अपनी कार खड़ी करने के लिए, एक संदूक के प्रकार के ढाँचे जैसा एक अस्थाई स्थान तिरपाल की सहायता से बनाना चाहती है, जो कार को चारों ओर से और ऊपर से ढक ले (सामने वाला फलक लटका हुआ होगा जिसे घुमाकर ऊपर किया जा सकता है)। यह मानते हुए कि सिलाई के समय लगा तिरपाल का अतिरिक्त कपड़ा नगण्य होगा, आधार विमाओं 4 मीटर x 3 मीटर और ऊँचाई 2.5 मीटर वाले इस ढाँचे को बनाने के लिए कितने तिरपाल की आवश्यकता होगी? |
|
Answer» Answer: ढांचे को बनवाने के लिए 47 मी² तिरपाल की आवश्यकता होगी।Step-by-step explanation: दिया है : ढांचे के लिए विमाएं हैं, l= 4 मी , b = 3 मी ,h = 2.5 मी ढांचे को बनवाने के लिए तिरपाल का अभिष्ट क्षेत्रफल = कार की (चार भुजाओं का क्षेत्रफल + ऊपरी भाग का क्षेत्रफल) = 2 (l+ b) × h + lb= [2(4 + 3) × 2.5 + 4 × 3] = 2 × 7 × 2.5 + 12 = 35 + 12 = 47 मी² अतः , ढांचे को बनवाने के लिए 47 मी² तिरपाल की आवश्यकता होगी।आशा है कि यह उत्तर आपकी मदद करेगा।
