Question

Sarita spend 65% of her salary and rest she save if we save rupees 2940 per month what is her annual salary

Answer 1

Let Annual salary = a

Salary she spends  = 65%

                                 = ( 100 - 65) 

Salary she saves     =  35%


Given Salary she saves = 2490 

                    35/100 * a  = 2490


On cross multiplication, we get

   a = 2940 * 100/35

      = 8400


Her Annual Salary = 8400 rupees.


Hope this helps!

Answer 2

let Sarita's annual salary be x

according to question ,
she spends 65%
which is , 65/100× x = 65x/100 => 13x/20 of the annual salary

now, money she earns - money she spends = money she saves

x - 13x/20 = 2940 rs
(20x-13x)/20 = 2940
7x/20 = 2940
x = (2940×20)/7 => 58800/7 => 8400 rs
hope this helps
