Answer:
The amount he saves each month is Rs(5a-2b).
Step-by-step explanation:
The given problem is very simple, we are given the amount of money that the person earns in a month and the amount of money he spends every month. Inorder to find the amount of money that he saves in a month we need to subtract the amount he spends from the amount he earns.
the amount he earns= Rs(7a+3b)
the amount he spends=Rs(2a+5b)
The amount he saves=Rs(7a+3b)-Rs(2a+5b)=Rs(7a+3b-2a-5b)=Rs(5a-2b)
