Answer the following questions.
17) What is Ram's salary?
a) 45000 b) 60000 c)90000 d)135000 ​

Answer 1

Explanation:

Let Ram's salary = ₹ x

Money donated to NGO = (2/3) of x

Money spent on food items = (1/5) of x

Other expenses = (1/5) of x

Balance amount = ₹ 9000

`x - ((2)/(3)x+(1)/(5)x+(1)/(15)x) = 9000\\\\\\x - ((2*5)/(3*5)x+(1*3)/(5*3)x+(1)/(15)x)=9000\\\\\\x-(10x+3x+1x)/(15)=9000\\\\\\x-(14)/(15)x=9000\\\\\\(15)/(15)x-(14)/(15)x=9000\\\\\\(1)/(15)x=9000`

x = 9000 * 15

x = ₹ 135000
