Amount he had = a
Amount he spent = a x 80/100 = 0.8a ............(1)
Amount left with him = a - 0.8a = 0.2a
Donates = 0.2 x 7/100 = 1.4a/100 = 0.014a .............(2)
Total he spends = 0.8a + 0.014a = 0.814a
remaining with him = 6510
a - 0.814a = 6510
0.186a = 6510
a = 6510/0.186= 35000
Monthly earning of the person = Rs.35000
