answer: she left with rs( 2000 - 17a + 2b)
Step-by-step explanation:
Given:-
Ritika spends (9a-b) rupees for a skirt, (6a+2b) rupees for a mobile and (2a- 3b) rupees for chocolates.She had Rs. 2000 with her.
To find :-
How much money will she be left with?
Solution :-
Given that
Total amount of Ritika = Rs. 2000
Money spent on a skirt = Rs. (9a-b)
Money spent on a mobile = Rs. (6a+2b)
Money spent on chocolates = Rs. (2a-3b)
Total money spent on all
=> (9a-b)+(6a+2b)+(2a-3b)
=> 9a-b+6a+2b+2a-3b
=> (9a+6a+2a)+(-b+2b-3b)
=> 17a+(2b-4b)
=> 17a+(-2b)
=> 17a-2b
Total amount spent by her = Rs. 17a-2b
Remaining money = Total money-Spent money
=> 2000 - (17a-2b)
=> 2000-17a+2b
Remaining money = Rs. (2000-17a+2b)
Answer:-
The money left with Ritika is
Rs. (2000-17a+2b)
