Question

Rohan donated 10 1 of his salary to an orphanage, 3 1 of his salary spent on food, 4 1 of salary on rent and electricity and 20 1 of his salary on telephone. This month he donated Rs.5000 in Prime Minister relief fund. He was left with Rs.3000 with him, find his monthly salary. What values are being promoted ?​

Answer 1

Answer:

Let Ram's salary be x. Then

x = x/10+x/3+x/4+x/10+5000+3000

where

x/10 = amount donated to orphanage

x/3 = amount spent on food

x/4 = amount spent on rent

x/20 = amount spent on telephone

5000 = amount donated to PM Relief Fund and

3000 = balance

The LCM of 10, 3, 4, and 20 is 60.

Thus, x = (6x+20x+15x+3x+300000+180000)/60

or 60x = 44x + 480000

60x-44x = 480000

or 16x = 480000

x = 480000/16 = 30,000

Thus, Ram's monthly salary is Rs. 30,000

Answer 2

Answer:

Let Ram's salary be x. Then

x = x/10+x/3+x/4+x/10+5000+3000

where

x/10 = amount donated to orphanage

x/3 = amount spent on food

x/4 = amount spent on rent

x/20 = amount spent on telephone

5000 = amount donated to PM Relief Fund and

3000 = balance

The LCM of 10, 3, 4, and 20 is 60.

Thus, x = (6x+20x+15x+3x+300000+180000)/60

or 60x = 44x + 480000

60x-44x = 480000

or 16x = 480000

x = 480000/16 = 30,000

Thus, Ram's monthly salary is Rs. 30,000
