His weekly income is:
+7890+%2F+3+=+2630+
His daily income for a 6-day week is:
+2630+%2F+6+=+438+%2B+1%2F3+
His income for 5 days is:
+5%2A%28+438+%2B+1%2F3+%29+
+2190+%2B+5%2F3+=+2191+%2B+2%2F3+
Rs 2191 + 2/3
----------------
check answer:
Working it backwards:
+%28+2191+%2B+2%2F3+%29+%2F+5+=+438+%2B+1%2F5+%2B+2%2F15+
+%28+2191+%2B+2%2F3+%29+%2F+5+=+438+%2B+5%2F15+
+438+%2B+5%2F15+=+438+%2B+1%2F3+
+6%2A%28+438+%2B+1%2F3+%29+=+2628+%2B+2+
+2628+%2B+2+=+2630+
+3%2A2630+=+7890+
OK
