Answer:

Rs. paise
x y
-
7 20

(x-1-7) (100+y-20)

x-8 y+80

x-8 = 3y

y+80 = 3x

x = 29

y = 7

x+y = 36

I have actually made two columns one for Rupees one for Paise! Here messed up that format! Anyway, I divided it into Rupees and Paise separately instead of converting the entire thing into paise! That way we are getting two variable but only one eqation.
