Let w = weekly income
10%25+of+weekly+income++=+%7B%7B%7B.1w
Remaining is .9w
25% of .9w is .25%2A.9w+=+.225w
given:
.1w+%2B+.225w is subtracted from weekly income
w+-+%28.1w+%2B+.225w%29+=+540
w+-+.1w+-+.225w+=+540
w+-+.325w+=+540
w%281+-+.325%29+=+540
w+=+540%2F.675
w+=+800
Weekly income is RS800
