Answers
Answer:
1. Rs.200
2. 30 bowls
Step-by-step explanation:
1. Cost of potatoes = 2×30 = 60 rs.
cost of tomatoes = 2×45 = 90 rs.
cost of apple = 0.5×100 =. 50 rs.
total cost = 60+90+50 = 200 rs.
2. 7litres and 500ml = 7500ml
No. of bowls that can be filled = 7500ml ÷250ml = 30 bowls
Step-by-step explanation:
Solution :-
1)
The cost of 1 kg potatoes = Rs. 30
The cost of 2 kg potatoes = 2×30 = Rs. 60
The cost of 1 kg tomatoes = Rs. 45
The cost of 2 kg tomatoes = 2×45 = Rs. 90
The cost of 1 kg apples = Rs. 100
The cost of 500 grams of apples = 100/2 = Rs. 50
Total amount to be paid to the shopkeeper
= 60 + 90 +50
= Rs. 200
The amount that Reshma will pay to the shopkeeper = Rs. 200
2)
The capacity of the utensil = 7 l and 500 ml
We know that
1 litre = 1000 ml
7 litres = 7×1000 ml = 7000 ml
Total mango shake in the given utensil
= 7000+500 ml
= 7500 ml
The capacity of the given bowl = 250 ml
Number of required bowls to be filled 7500 ml mango shake
= Total mango shake in the utensil / Capacity of one bowl
= 7500/250
= 750/25
= 30
Total number of bowls of 250 ml are needed to fill the total mango shake is 30
