Step-by-step explanation:
Let his salary be X.
After losing 10% salary he has X-(10%of X)=
=X-X/10 = 9X/10.
He spent 7% of the remaining salary.
7% of 9X/10 = 9X/10 × 7/100= 63X/1000.
Remaining salary after spending 7%
9X/10-(63X/1000) = 837X/1000
The finally remaining salary is Rs.140
So, 837X/1000= 140
Total salary X = Rs.160.264
