Answer:
Step-by-step explanation:
Step 1: Finding total money spent:
Money Spent by Savitri =1000 (for grocery) +500 (for clothes) +400 (on education) =Rs.1900
Step 2: Finding the remaining money by subtracting the money spent and adding the money received
Money received by Savitri as a gift =Rs.200
Therefore total money now =x+200
Now, we know that Money remaining = Total money - Money Spent
=x+200−1900
=x−1700
Therefore, the money left with Savitri is Rs. (x−1700)
