Answers
Answer:
(1) Rs.1300
(2) 1hour 15minutes
(3) Rs.4,200
(4) 600ml
Step-by-step explanation:
(1) Cost of Diesel for per Liter or 1 liter is Rs.65 .
Shantubhai fills 20 liters of Diesel in his Car.
Shantubhai have to pay = Cost of Diesel per liter × Liter of Diesel fills
Shantubhai have to pay = 65 × 20
Shantubhai have to pay = 1300
Hence, Shantubhai have to pay Rs.1300.
(2) Kinjal did her Homework from 8:15pm to 9:30pm.
Time spent by Kinjal = Difference between starting and Finishing time.
Upto 8:15 to 9:00 = 45 minutes
Upto 9: 00 to 9:30 = 30 minutes
Total Time spent = 45 minutes + 30 minutes
Total Time spent = 1hour 15minutes
Hence, Kinjal spent 1hour and 15minutes in doing her Homework.
(3) Preeti earns 140 in 1 day.
Total money earn by Preeti in 30 days = Earn 1 day × No. of Days
Total money earn by Preeti in 30 days = 140 × 30
Total money earn by Preeti in 30 days = 4,200
Hence, Preeti earns Rs.4,200 in 30 days.
(4) Bottle contains 1 liter of water or we can say 1000ml of water.
Amisha drank 250ml of water.
Her friend drank 150ml of water.
Total ml of water drank by both Amisha and her friend is 250+150 = 400ml of water.
Now,
Water left in bottle = Water contains in bottle - Water drank by both Amisha and her friend.
Water left in bottle = 1000ml - 400ml
Water left in bottle = 600ml
Hence, only 600ml of water left in the bottle.
