Explanation:

Let the earlier expenditure of Aman be Rs.100
Therefore present expenditure of Aman = 100 – 25 = Rs.75
saman also has to match his expenditure to Rs.75
Therefore, Rs.75 is 25% more than the saman’s earlier expenditure.
Therefore earlier expenditure of saman =75/125× 100=Rs 60
Therefore total of their earlier expenditures = Rs.100 + Rs.60 = Rs.160
Total of their present expenditures = Rs.75+ Rs.75 = Rs.150
ACTUAL:
If the total of their earlier expenditures was Rs.160, then the total of their present expenditures is
Rs.150.
total of their present expenditures =150/160 × 800 = Rs.750
