So, there are 1071 books in the library now.
Problem 2 :
In a music competition, 256 boys and 278 girls participated. Find the total number of students participated in the competition.

So, 534 students participated in the competition altogether.
Problem 3 :
William gave $1250 to his wife from his salary. After having given $1250, if he had $1080 left, find William's salary.

So, the minimum passing marks in the examination is 50.
Problem 5 :
Johnson read 5 pages of a story book on Saturday. He read 3 more pages on Sunday than on Saturday. How many pages of the story book did he read altogether on these two days ?
Number of pages read on Saturday :
Number of pages read on Sunday :
= 5 + 3
Number of pages read on Saturday and Sunday altogether :
= 5 + 8
Problem 6 :
James started his journey in a plane at A.M. on Tuesday and finished at 3 P.M. on Wednesday. How long did James have his journey in the plane?
From 11 A.M. Tuesday to 11 A.M. Wednesday is 24 hours.

Then, total hours is
= 24 + 4
So, James had his journey in the plane for 28 hours.
Problem 7 :
A taxi driver charges a flat rate of $20 and $12 for a distance less than or equal to 5 miles, $10 for a distance from 6 to 10 miles and $8 for a distance from 11 to 15 miles. How much has to be paid for a travel of 13 miles in that taxi?
Amount has to be paid for 13 miles :
= 20 + 12 + 10 + 8
Problem 8 :
Cameroon started writing an exam at 3:25 P. M. and finished at 5:40 P.M. How long did Cameroon write the exam?
From 3:25 P.M. to 5:25 P.M. is 2 hours.
From 5:25 P.M. to 5:40 P.M. is another 15 minutes.
Then, the total time is
= 2 hours + 15 minutes
= 2 hours 15 minutes
So, Cameroon wrote the exam for 2 hours 15 minutes.
Problem 9 :
In a game, player A scored 55 points, player B scored 15 points more than player B, player C scored 25 points more than player B and player D scored the same as C. Find the total points scored by all the three players.
Points scored by player A :
Points scored by player B :
= 55 + 15
Points scored by player C :
= 70 + 25
Points scored by player D :
Total points scored by all the three players :
= 55 + 70 + 95 + 95
Problem 10 :
PQRS are four places. Distance from P and Q is 75 miles, distance from Q to R is 15 miles more than the distance from P to Q and the distance from R to S is four-third of the distance from Q to R. Find the total distance from place P to place S.
Distance from P to Q :
= 75 miles
Distance from Q to R :
= 75 + 15
= 90 miles
Distance from R to S :
= 4/3 ⋅ (Distance from Q to R)
= 4/3 ⋅ 90 miles
= 4 ⋅ 30
= 120 miles
Total distance from P to S :
= (P to Q) + (Q to R) + (R to S)
= 75 + 90 + 120
= 285 miles
