Runs scoredFrequencyCumulative Frequency
0-2044
20-40610
40-60515
60-80318
80-100422

Total frequency (N) = 22

⇒ `"N"/2` = 11

So, 40-60 is the median class

⇒ `l+\frac{(\frac{N}{2})-cf}{f}\times h`

⇒ `40+\frac{11-10}{5}\times20`

⇒ 44 runs

Therefore, the median runs scored is 44

Explain the Role of ‘Justice Party’ in Boycotting of Council Elections | bzziii.com

By admin -
answer source Question Read the source given below and answer the questions that follows: Source : The Movement in the Towns The movement started with middle-class participation in the cities. Thousands of students left government-controlled schools and colleges, headmasters and teachers resigned, and lawyers gave up their legal practices. The council elections were boycotted in most provinces except Madras, where the Justice Party, the party of the non-Brahmans, felt that entering the council was one way of gaining some power–something that usually only Brahmans had access to. The effects of non-cooperation on the economic front were more dramatic. Foreign goods were boycotted, liquor shops picketed, and foreign cloth burnt in huge bonfires. The import of foreign cloth halved between 1921 and 1922, its value dropping from Rs. 102 crore to Rs. 57 crore. In many places merchants and traders refused to trade in foreign goods or finance foreign trade. As the boycott movement spread...

Fraction becomes 9/11, If 2 is Added to Both the Numerator and Denominator. If 3 is Added to Both the Numerator and the Denominator, it Becomes 5/6. Find the Fraction. | Bzziii.com

A fraction becomes `9/11`, if 2 is added to both the numerator and denominator. If 3 is added to both the numerator and the denominator, it becomes `5/6`. Find the fraction. SOLUTION Let Numerator be x & Denominator be y So, Fraction is = `x/y` Given that, If 2 is added to both the numerators and denominator, fraction becomes `9/11` `"Numerators + 2"/"Denominator + 2"`= `9/11` `"x+ 2"/"y + 2"`= `9/11` 11 (`x + 2`) = 9 (`y + 2`) 11`x` + 22 = 9`y` + 18 11`x` - 9`y` = 11 - 22 11`x` - 9`y` = -4 .......(1) Also, Given that if 3 is added to both the numerator and the denominator, fraction become `5/6` `"Numerators + 3"/"Denominator + 3"`= `5/6` `"x+ 3"/"y + 3"`= `5/6` 6 (`x + 3`) = 5 (`y + 3`) 6`x` + 18 = 5`y` + 15 6`x` - 5`y` = 15 - 18 6`x` - 5`y` = - 3 .......(2) Hence, our equations are 11`x` - 9`y` = -4 .......(1) 6`x` - 5`y` = - 3 .......(2) From equation (1...

Researchers once surveyed college students on their Facebook use. The following two-way table displays data for the sample of students who responded to the survey. Approximately what percent of students in the sample do not use Facebook? Round your answer to the nearest percent. Age Uses Facebook Does not Uses Facebook 18 to 22 78 4 23+ 70 67 Approximately what percent of students in the sample do not use Facebook? Round your answer to the nearest percent. SOLUTION The number of students who do not use facebook is calculated by counting the total number of students in the row shown in the blue box. We add to find the total number of students in that row to get the total number as 71. Age Uses Facebook Does not Uses Facebook Total 18 to 22 78 4 82 23+ 70 67 137 Total 148 71 219 The percentage is calculated by dividing 71 with the total number of students which is 219 So, the percentage is `\frac{71}{219}` = 0.3242 `\times` 100  = 32.4221971 = 0.3242×100 = 32.42% So, app...
