Question

A mans total income in the first six months of the year is Rs 6000 and in the last six months of the year is Rs 7200 .Find his monthly average income for that year

Answer 1

The average monthly income of a man in that year is Rs 11,00

Step-by-step explanation:

Given as :

The total income of a man in the first six months in a year = x = Rs 6000

The total income of a man in the last six months in a year = y = Rs 7200

Let The average monthly income of a man in that year = Rs z

According to question

Total income of man in that year = total income of a man in the first six months +  total income of a man in the last six months

i.e Total income of man in that year = Rs x + Rs y

Or, Total income of man in that year = Rs 6000 + Rs 7200

∴  Total income of man in that year = Rs 13200

Again

The average monthly income = $\dfrac{Total income of man in a year}{Total number of months in a year}$

i.e z = $\dfrac{Rs 13200}{12}$

∴  z = Rs 11,00

So, The average monthly income of a man in that year = z = Rs 11,00

Hence, The average monthly income of a man in that year is Rs 11,00 Answer

Answer 2

Answer:

Step-by-step explanation:

Total income of the year = 6000+7200= 13200

Thus, the average income is 13200/12 = 1100
