In a cricket matchKumble took three wickets less than twice the number...
let the no of wickets taken by srinath be x 

no of wickets taken by kumble 2x-3 

product of their wickets = 20 

so X(2X-3) = 20 

2xsquare - 3x - 20 = 0 

2xsquare - 8x + 5x -20 = 0 

2x(x-4) + 5(x-4) = 0 

(2x+5)(x-4) = 0 

x = -5/2 x = 4 

-5/2 rejected because wickets cannot be negative so no of wicketsvtaken by srinath = 4 and kumble is 5

In a cricket matchKumble took three wickets less than twice the number...
Let the number of wickets taken by Srinath be x then the number of wickets taken by Kumble will be 2x−3
According to question, x (2x−3) = 20
⇒ 2x2−3x−20 = 0
⇒ 2x2−8x+5x−20 = 0
⇒ 2x(x−4)+5(x−4) = 0
⇒ (x−4)(2x+5) = 0
⇒ x−4 = 0and 2x+5 = 0
Therefore, number of wickets taken by Srinath is 4.
Then number of wickets taken by Kumble = 2 x 4 - 3 = 5

Similar Class 10 Doubts

Read the extract given below and answer the questions that follows:There are many activities that are undertaken by directly using natural resources. When we produce a good by exploiting natural resources, it is an activity of the primary sector. Since most of the natural products we get are from agriculture, dairy, fishing, forestry, this sector is also called agriculture and related sector. The secondary sector covers activities in which natural products are changed into other forms through ways of manufacturing that we associate with industrial activity. It is the next step after primary. The product is not produced by nature but has to be made and therefore some process of manufacturing is essential. After primary and secondary, there is a third category of activities that falls under tertiary sector and is different from the above two. These are activities that help in the development of the primary and secondary sectors. These activities, by themselves, do not produce a good but they are an aid or a support for the production process. The various production activities in the primary, secondary and tertiary sectors produce a very large number of goods and services. Also, the three sectors have a large number of people working in them to produce these goods and services. The value of final goods and services produced in each sector during a particular year provides the total production of the sector for that year. And the sum of production in the three sectors gives what is called the Gross Domestic Product (GDP) of a country. It is the value of all final goods and services produced within a country during a particular year. GDP shows how big the economy is.Q. Match the following list of occupations with their sectors
