L.C.M. and H.C.Fe. What will be the total number of integers between 100 and 200can be divided by both 9 and 6?(al 5bl 6(c) 7s(d) 8 |
|
Answer» Any number that is divisible by 9 and 6 is also divisible by their LCM, i.e., 18.Now, on dividing 100 by 18, the remainder = 10. Thus, the smallest number greater than 100 that is divisible by 18 =100+(18−10)=108.100+(18−10)=108.Similarly, remainder on dividing 200 by 18 = 2, and the largest number smaller than 200 that is divisible by 18 = 198.Number of numerals between 108 and 198 (both inclusive) that are divisible by 18 =(198−108)/18+1=6.(198−108)/18+1=6.Therefore,there are 6 numbers between 100 and 200 that are divisible by both 6 and 9. |

3.What is the problem with the periodisation of Indian history that James Mlloffers?hirtnrinne aet from old newspapers be different |
|
Answer» In 1817, James Mill, a Scottish economist and a political philosopher, published A History of British India in three volumes. He divided Indian history into three periods—Hindu, Muslim and British. It has been argued by many historians that it is not correct to periodise Indian history on the basis of religion of the rulers. For example, when the Hindu kings ruled in ancient India, many religions existed peacefully. The same is also true for mediaeval India. It was not correct to periodise mediaeval India as Muslim History because people belonging to different faiths existed during this time. Such periodisation which was based on the religion of the rulers suggests that the lives, practices and culture of the other people do not matter. |

VOCABULARY How can you tell whether two ratios are equivalent? |
|
Answer» Ratiosexpress a relationship between two numbers. For example, the ratio 3:5, in terms of shots made and shots taken, means that three out of every five shots goes in. When you have multiple ratios, you may want to determine whether they are equal or if one of them is larger. Tocompare ratios, you need to have a common second number. By multiplying each ratio by the second number of the other ratio, you can determine if they are equivalent. |

than what it Was berore. Find he hune9. Using Euclid's division algorithm, find the HCF of 2160 and 3520fnd the value ofm |
|
Answer» Euclid's division algorithm: According to this the HCF of any two positive integers a and b, with a>b a= bq+r, 0 ≤ra= 3520 , b= 2160 On applying euclid's division Lemma for 2160 & 3520 3520 = (2160×1)+1360 Here, remainder= 1360≠0So take new Dividend as 2160 & divisior as 13602160 = (1360×1)+800Here, remainder= 800≠0So take new Dividend as 1360 & divisior as 8001360= (800×1)+560Here, remainder= 560≠0So take new Dividend as 800 & divisior as 560800 = (560×1)+240 Here, remainder= 240≠0So take new Dividend as 560 & divisior as 240560 = (240×2)+80 Here, remainder= 80≠0So take new Dividend as 240 & divisior as 80240 = (80×3)+0Here, the remainder is 0 & last divisor is 80. Hence , HCF of 2160 & 3520 is 80 |

What is the smallest number by which /5- 2 is to be multiplied to makerational number? Also find the number so obtained?19. |
|
Answer» To make rational number we have to multiply with its conjugate.Here conjugate of (√5 - √2) is (√5 +√2)(√5 - √2) (√5 +√2) (√5)² - (√2)² [(a+b)(a-b)= a² -b²]= 5 - 2= 3 3 is a rational number.Hence,the smallest number by which √5–√2 is to be multiplied to make it a rational number is √5+√2 and the number so obtained is 3. |
