Question

एक व्यक्ति अपनी आय का 20% खर्च करता है। यदि वह प्रतिमाह 5000 की बचत
करता है तो उसकी मासिक आय कितनी है?
​

Answer 1

Answer:

Let his monthly salary be x

He spend 20% of his salary, so we find 20% of x = x*20/100 = x/5

From here we can find his monthly saving, so his monthly saving is = x-x/5 = 4x/5

In question it is given that monthly saving is 5000 then we can put a equation here and that equation is

4x/5 = 5000. (now we will move 5 to RHS)

4x = 5000*5. (now we will move 4 to RHS by doing calculation

x = 5000*5/4

= 25000/4 = 6250

So his monthly salary is ₹6250
