Expenditure
0-100 100-200 200-300 300-400 400-500
Number of families
140
230
270
x
150​

Answer 1

Answer:

Ans is 210 as we know F1 is 270 an d f0 is 230 or F2 is x by l is 200 so h is 100 ;

240= 200+( 270-230)÷2(270) -230-x *100

40= 40÷ 540-230-x*100

2÷5=40÷310-x

629-2x=200

420=2x

x=210

Answer 2

Concept Introduction:

The value that frequently appears in a particular set is the definition of mode. In addition to mean and median, it is one of the three measures of central tendency. In other words, a data set's mode or modal value is the value or number that occurs most frequently.

Given: Number of families: $140,230,270,x,150$.

To Find:

We have to find the value of, x.

Solution:

According to the problem,

F$1$ is $270$ and f$0$ is $230$ or F$2$ is x by l is $200$ so h is $100$.

$240= 200+( 270-230)/2(270) -230-x *100$

$40= 40/540-230-x*100$

$2/5=40/310-x$

$629-2x=200$

$420=2x$

$x=210$

Final Answer:

The value of x is $210$.
