Given,Value of Mode = 38

and the class of Mode is between 30 to 40 or 30-40

We Know that,

Model = `l+\frac{f_{1}-f_{0}}{2f_{1}-f_{0}-f_{2}}\times h`

⇒ 38 = 30 + `"16 - 12"/"32 -12- x"` `\times`10

⇒ 38 - 30 = `"4"/"20- x"` `\times`10

⇒ 8 = `"4"/"20- x" ``\times`10

⇒ 8 (20 - x) = 40

⇒ 20 - x = `40/8`

⇒ 20 - x = 5

⇒ 20 - 5 = x

⇒ 15 = x

∴ x = 15

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...

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...
