How many days will he require to plant all 152 ofthem?(5) It is required to bring 740 cement bags to a cement sales centre.The maximum number of cement bags that can be transported in avehicle is 24. Find the number of trips the vehicle needs to make tobring all the cement bags to the centre

(1) To find the total number of people who visited the art exhibition on the first three days, you simply add the number of visitors for each day. So, 1320 (day 1) + 1567 (day 2) + 1624 (day 3) = 4511 visitors in total.

(2) To find out how many more yoghurts were produced in the second week than in the first week, you subtract the number of yoghurts produced in the first week from the number produced in the second week. So, 4124 (week 2) - 3788 (week 1) = 336 more yoghurts were produced in the second week.

(3) To find the total number of books in the library, you multiply the number of book racks by the number of shelves per rack and then by the number of books per shelf. So, 10 (racks) x 5 (shelves) x 30 (books) = 1500 books in total.

(4) To find out how many days the man will need to plant all 152 coconut plants, you divide the total number of plants by the number he can plant per day. So, 152 (plants) ÷ 8 (plants per day) = 19 days.

(5) To find the number of trips the vehicle needs to make to transport all 740 cement bags, you divide the total number of bags by the maximum number of bags that can be transported per trip. Since this will likely not result in a whole number, you round up to the nearest whole number because you can't make a fraction of a trip. So, 740 (bags) ÷ 24 (bags per trip) = 30.83, which rounds up to 31 trips.
