Explanation

If the rate of tax is 10% on, salary, then the  monthly salary of a person who pays Rs. 4500 tax per month is  Rs. 15000

Let us assume that the income of the man is Rs. y.

We are given that he pays 10% of his income as income tax, i.e.

His income tax = Rs. 10/100 × y.

We are given that he pays Rs. 1500 as income tax.

1500 = 10/100 × y

 y = 1500 x 10 = 15000.

Explanation

1/3 .x =1/6 + 100

x/3 = x/6 + 100

x/3 = x+600/6

20 = x+600

2x - x = 600

x = 600

Explanation

The prime numbers less than 50 are:

2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, and 47.

Explanation

Net percentage increase in Population = (2.5 - 0.5) = 2% each year.

Let the Original Population of the town be 100.

Population of Town after 1 year = (100 + 2% of 100) = 102.

Population of the town after 2nd year = (102 + 2% of 102 ) = 104.04

Now, % increase in population = 4.04 / 100 ×100 = 4.04%
