A man earns #3500 per month out of which he spends 15 percent on his children's education. If he spends additional #1950 on food, how much does he have left?

Answer 1

0.85*3500 - 1950 = 1025 (£?)
I never heard of a currency measured in #

Answer 2

15÷100×3500= 525
525+1950=2475
3500-2475=1025
final answer = 1025
