B) A grocer sold 5 kg of wheat flour at Rs 30 per kg and gained 20%. If he had sold it at Rs 27 per kg, what would be his gain or loss percent?

22.5%

Step By Step Explanation:

1) the amount which will be obtained when 5 kg of rice is sold for Rs30 per kg=150 kg

2) the amount which will be obtained when 5 kg of rice is sold for Rs27 per kg=135 kg

3)difference of Both the no. = 150-135

                                              = 15 kg

4) ans as percentage =  15% of 150

                                   =  22.5%

    WARNING:- NOT SURE WITH THE ANSWER

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
