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 ?

Solution :

To find the total number of books in the library now, add 1028 and 76.

=  1028 + 76

=  1104

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 ?

Solution :

To find the total number of students, add 1056 and 781.

=  1056 + 781

=  1837

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 ?

Solution :

To find the money in the beginning, add 1025 and 756.

=  1025 + 756

=  1781

So, William had \$1781 at first.

Problem 4 :

Solution :

=  600 + 150

=  750

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 ?

Solution :

Number of meatballs sold on Saturday :

=  1257

Number of meatballs sold on Sunday :

=  1257 + 158

=  1415

Number of meatballs sold on Saturday and Sunday altogether :

=  1257 + 1415

=  2672

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 ?

Solution :

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

=  32

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 ?

Solution :

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.

Solution :

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.
