Question

The monthly salary of a man is Rs 21000 is salary increases by 15% find his new monthly salary.​

Answer 1

Answer:

If there is a 15 % increase in monthly salary from Rs 21000, then the new salary is Rs 24150

Step-by-step explanation:

Given old monthly salary = Rs 21000

Percentage increase = 15%

Percentage increase = [ ( final salary - initial salary ) / initial salary] *100

let us take x as the new salary

That is,

$15 = \frac{x-21000}{21000} *100\\\\15*21000= 100x-2100000\\\\315000 = 100x - 2100000\\\\100x = 315000+2100000\\\\100x =2415000\\\\x = \frac{2415000}{100}\\\\= 24150$

So the new salary is Rs 24150

Answer:

24150 Rupees

Step-by-step explanation:

According to the information provided in the question it is given as

Monthly salary of a man  = Rs 21000

Increased by 15 %

We need to find the new salary

So this is the simple question of percentage first understand the meaning of percentage In mathematics, a percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%

So we find 15% of 21000

$\frac{15}{100} \times 21000$

Finding the lowest term

$=15\times 210$

( As 21000 and 100 are divisible by 100)

$=3150$

this is the increased amount per month

so  new  monthly salary = old salary + increment amount

                                        =21000+ 3150

                                        =24150 rupees

Hence new salary per month is =24150 rupees
