Problem 1 :
There were 1028 books in the library. We bought 76 more books for the library today. How many books are there in the library now ?
To find the total number of books in the library now, add 1028 and 76.
= 1028 + 76
So, there are 1104 books in the library now.
Problem 2 :
In an art competition, 1056 boys and 781 girls took part. How many students took part in the competition altogether ?
To find the total number of students, add 1056 and 781.
= 1056 + 781
So, 1837 students took part in the competition altogether.
Problem 3 :
William gave $1025 to his wife. After having given $1025 to his wife, he had $756 left. How much money did he have at first ?
To find the money in the beginning, add 1025 and 756.
= 1025 + 756
So, William had $1781 at first.
Problem 4 :
In an Examination, Jack scored 600 marks and received grade B. If Jack had scored 150 more marks, he would have received grade A. Find the score for grade A.
To find the score for grade A, add 600 and 150.
= 600 + 150
So, the score for grade A is 750.
Problem 5 :
Jack sold 1257 meatballs on Saturday. He sold 158 more meatballs on Sunday than on Saturday. How many meatballs did he sell altogether on these two days ?
Number of meatballs sold on Saturday :
Number of meatballs sold on Sunday :
= 1257 + 158
Number of meatballs sold on Saturday and Sunday altogether :
= 1257 + 1415
So, Jack sold 2672 meatballs altogether on Saturday and Sunday.
Problem 6 :
Joey participated in a dance-a-thon. His team started dancing at 10 A.M. on Friday and stopped at 6 P.M. on Saturday. How many hours did Joey’s team dance ?
From 10 A.M. Friday to 10 A.M. Saturday is 24 hours.
From 10 A.M. Saturday to 6 P.M. Saturday is another 8 hours.
Then, total hours is
= 24 + 8
So, Joey's team danced for a total of 32 hours.
Problem 7 :
Jeff left Hartford at 2:15 P.M. and arrived in Boston at 4:45 P.M. How long did the drive take him ?
From 2:15 P.M. to 4:15 P.M. is 2 hours.
From 4:15 P.M. to 4:45 P.M. is another half hour.
Then, the total time is
= 2 hours + 0.5 hours
= 2.5 hours
= 2 hours 30 minutes
So, the drive took him for 2 hours 30 minutes.
Problem 8 :
Distance from place A to B is 50 miles, distance from place B to place C is two times the distance from place A to place B and the distance from Place C to place D is three-fourth of the distance from place B to place C. Find the distance from place A to place D.
Distance from place A to place B :
= 50 miles
Distance from place B to place C :
= 2 ⋅ (Distance from A to B)
= 2 ⋅ 50 miles
= 100 miles
Distance from place C to place D :
= 3/4 ⋅ (Distance from C to D)
= 3/4 ⋅ 100 miles
= 3 ⋅ 25
= 75 miles
Total distance (A to D) :
= (A to B) + (B to C) + (C to D)
= 50 + 100 + 75
= 225 miles
So, the distance from Place A to place D is 225 miles.
