Question

. Priyanka saves 60% of the money given by her father on her birthday and spends 25% on a doll,which costs Rs 139.50. If her father gave 5% of his monthly salary to spend on the birthday, whatis the monthly salary of her father?​

Answer 1

Answer:

25% = 139.5

5% =139.5/5

     =27.9

60% = 27.9*12

60%=355.8

85% = 60%+25%

85%=495.3

100%= 85%+15%

15% = 5% * 3

15% =27.9*3

15% =83.7

100%=83.7+495.3

100% =579

5% of father's money = 579

100% of father = 579*20

100% = salary

Father's Salary=11,580

Step-by-step explanation:

We know that 25% = 139.5

With this using the unitary method we can find 60%

We have

25%=139.5

Divide 25 by 5 to know the value for 5% with which we can find 60%

5% =139.5/5

     =27.9

Now multiply 5% with 12 to find value for 60%

60% = 27.9*12

        =355.8

We have to find the total amount given to Priyanka = 100%

We know that 60% = 355.8 and 25%= 139.5

With this we can add them to find 85%=495.3

100%-85%= 15%

To find 15% we can use unitary method

5% = 27.9

Then, 15% = 83.7

100%-85%= 15%

100%=495.3+83.7

        =579

5% of father's salary = 100% of priyanka's money

100%=579

So, 5% of father's money =579

With this using unitary method we can find father's salary that is 100%

5%=579

Then 100% = 579*20

Father's salary = 11,580
