Answer 1

Solution

_________

Let the salary was ₹100

Total expenditure= 25 + 20 + 10 = 55

Remaining money = 100 - 55 = 45

Tax paid = 75

Last remaining money = 465

Now see, before the paying of taxes he had the remaining money ₹465 + 75 = 540

So, now using Unitary Method

If the remaining money is ₹ 55 the salary was ₹100

If the remaining money is ₹540, the salary was = (100/55) x 540

= ₹981.82 (app.)
