Answer:
1) ₹913.00
2) ₹ 379.80
Step-by-step explanation:
1) Cost of the first meal = ₹ 42.20
No. of people = 9
Total cost = ₹ 42.20× 9
= ₹ 379.80
Cost of second meal = ₹ 47.60
No. of people = 7
Total cost = ₹ 47.60× 7
= ₹333.20
Total people = 20
People who have already ordered meal = (7+9)= 16
People who are left = 20-16
= 4
Cost of third meal = ₹50
No. of people = 4
Total cost = ₹50× 4
= ₹200
Money spent by the group on first meal = ₹379.80
Money spent by the group on sec meal = ₹333.20
Money spent by the group on third meal= ₹200
Total money spent by the group on all meal=
₹ 379.80
+ ₹ 333.20
+ ₹ 200.00
₹ 913.00
Therefore, the total money spent by 20 people is ₹913.00 .
2) Cost of the first meal = ₹ 42.20
No. of people = 9
Total cost = ₹ 42.20× 9
= ₹ 379.80
Therefore, the money spent by 9 people who ordered same meal is ₹ 379.80
