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

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

Arun and Vijay Are Partners In A Firm Sharing Profits And Losses In The Ratio of 5:1, Machinery Reflected In The Balance Sheet Is Overvalued -

Arun and Vijay are partners in a firm sharing profits and losses in the ratio of 5:1.  Balance Sheet (Extract)  Liabilities Amount (Rs.) Assets Amount (Rs.) Machinery 40,000 If the value of machinery reflected in the balance sheet is overvalued by 33 `1/3`%, find out the value of Machinery to be shown in the new Balance Sheet:  (A) ₹ 44,000  (B) ₹48,000  (C) ₹ 32,000  (D) ₹30,000  SOLUTION (D) ₹30,000  Explanation: Machinery is overvalued Value by 33 `1/3`% of 40,000 Here, 33 `1/3`% as a fraction = `\frac{33\frac{1}{3}}{100}` Converting the mixed fraction to an improper fraction, we get = `\frac{\frac{100}{3}}{100}`  = `100/300` Simplifying this, we get = `100/300` = `1/3` = `100/300` of z = 40,000-z Because, 40,000 is overvalued Value, we will minus the real value from 40,000. = `"100x"/"300"` + `"300z"/"300"` = 40,000 = `"400z"/"300"` = 40,000 = 40,000 `\times` `300/400` = z ∴ z = 30,000 4 5
