The monthly salary of a salesman of a departmental store is Rs 12,500 and an additional payment of 0.5 % on the total monthly sale is provided as commission. i) Calculate his total income in a month if he makes a total sale of Rs 7,20,000 in that month.

ii) What should be his total sale in the next month so that he can receive a total income of Rs 20,000 in the month?

i.

ii.

Step-by-step explanation:

Given

Commission = 0.5% of Monthly Sales

Calculating his total income is total sales is  Rs 720,000

Substitute (0.5% of Monthly Sales) for Commission

Substitute Rs 720,000 for Monthly Sales and Rs 12,500 for Salary

Convert % to decimal

Calculating his total sales if total income = Rs 20,000

Recall that;

Substitute Rs 20,000 for Total Income; Rs 12,500 for Salary and (0.5% of Monthly Sales) for Commission

Subtract Rs 12,500 from both sides

Divide both sides by 0.5%

Convert % to decimal

the answer is a. q=6,r=6√2

step-by-step explanation:

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
