Q2: To earn money on a video website, Harry needs at least 1,000 subscribers and 4,000 watched hours on his channel account. Harry had 345 subscribers. He then uploaded his first adventure video and gained another 511 subscribers. How many more subscribers does he need to start earning money?
Ans: Total number of subscribers needed to earn money = 1000
Number of subscribers Harry has = 345 + 511 = 856
Number of subscribers he needed more = 1000 – 345 – 511 = 144
He needs 144 more subscribers to start earning money.
Q3: There are 1,354 animals in one barn. There are 574 goats, 346 cows, and the rest are horses. If 89 horses were sold, how many horses are left in that barn?
Ans: Total number of animals in a barn = 1354
Number of goats = 574
Number of cows = 346
Total number of animals except for horses = 574 + 346 = 920
Therefore, number of horses= 1354 - 920 = 434
Number of horses sold= 89
Therefore, number of horses left= 434-89= 345
Q4: Mr. Smith has 238 eggs in the warehouse. He collected another 122 eggs from his chickens yesterday. As he arranged all the eggs in trays, he accidentally dropped 28 eggs on the ground. How many unbroken eggs were left? Among the eggs left were 126 brown eggs; how many were white eggs?
Ans: Total number of eggs in Mr. Smith's warehouse = 238
Total number of eggs he collected from his chickens = 122
Total number of eggs Mr. Smith has = 238 + 122 = 360
Number of eggs he dropped = 28
Number of eggs left = 360 - 28 = 332There were 332 unbroken eggs left.
Number of brown eggs = 126Therefore, number of white eggs = 332 – 126 = 206
There were 206 white eggs left.
Q5: There are 285 storybooks and 168 picture books on the library shelves. The librarian borrowed 73 books for a classroom reading session.
How many books are left on the library shelves?
Ans: To find how many books are left on the shelves, we first need to find the total number of books and then subtract the borrowed ones.
Total number of books = Number of storybooks + Number of picture books
Total number of books = 285 + 168
Total number of books = 453Number of books borrowed = 73
Number of books left = Total number of books – Number of books borrowed
Number of books left = 453 – 73
Number of books left = 380So, there are 380 books left on the library shelves.
Q6: A fruit seller had 246 apples. He sold 138 apples in the morning and 52 in the evening. How many apples does he still have?
Ans: To find how many apples are left, we need to subtract the total apples sold from the total apples he had.
Total apples sold = Apples sold in morning + Apples sold in evening
Total apples sold = 138 + 52
Total apples sold = 190Apples left = Total apples – Total apples sold
Apples left = 246 – 190
Apples left = 56So, the fruit seller has 56 apples left.
Q7: There were 127 drawings from Class A, 189 from Class B, and 94 from Class C. How many drawings were submitted in total?
Ans: To find the total number of drawings submitted, we need to add all the drawings from each class.
Total drawings = Drawings from Class A + Drawings from Class B + Drawings from Class C
Total drawings = 127 + 189 + 94
Total drawings = 410So, there were 410 drawings submitted in total.
Q8: There were 420 students going for a picnic. 188 students travelled by Bus A and 197 travelled by Bus B. How many students travelled by Bus C?
Ans: To find how many students travelled by Bus C, we need to subtract the number of students in Bus A and Bus B from the total number of students.
Students in Bus A and Bus B = 188 + 197
Students in Bus A and Bus B = 385Students in Bus C = Total students – Students in Bus A and Bus B
Students in Bus C = 420 – 385
Students in Bus C = 35So, 35 students travelled by Bus C.
Q9: At the book fair, 356 visitors came in the morning and 478 in the afternoon. If the hall can hold 900 people in a day, how many more people can still enter before reaching the limit?
Ans: To find how many more people can still enter, we need to subtract the total number of visitors so far from the hall’s capacity.
Total visitors so far = Visitors in the morning + Visitors in the afternoon
Total visitors so far = 356 + 478
Total visitors so far = 834Remaining capacity = Total capacity – Total visitors so far
Remaining capacity = 900 – 834
Remaining capacity = 66So, 66 more people can still enter the hall.
Q10: A farmer picked 235 mangoes from one tree and 198 from another. He sold 260 mangoes in the market. How many mangoes does he still have?
Ans:To find how many mangoes the farmer still has, we first find the total mangoes picked and then subtract the mangoes sold.
Total mangoes picked = Mangoes from first tree + Mangoes from second tree
Total mangoes picked = 235 + 198
Total mangoes picked = 433Mangoes left = Total mangoes picked – Mangoes sold
Mangoes left = 433 – 260
Mangoes left = 173So, the farmer still has 173 mangoes.
