Answer 1

Hey sup!

As per the question,

Let the monthly salary be 100x

Spends=80%.
Remaining=100x(1-80/100)=20x.

Donation=7%.
Remaining=20x(1-7/100)
=20x*93/100.
=1860x/100.
=18.60x

Also Remaining=6510.

So, 18.60x= 6510.
100x=6510/18.60 × 100.
=350×100.
=35000.

So the monthly salary is 35000Rs

Hope it helps
