**Problem 8 : **

In a running race, Kevin reached the target in 2 minutes 5 seconds and lost the first price by 12 seconds. In what time should he have completed the race to get the first price ?

**Problem
1 : **

Mr. Jacob’s class has 27 students. Only 23 were present on Tuesday. How many were absent ?

**Solution : **

To find the number of students absent, subtract 23 from 27.

= 27 - 23

= 4

So, there were 4 students absent on Tuesday.

**Problem 2 : **

In a library, there are 1028 books today. If the librarian had bought 76 books yesterday, how many books would have been in the library day before yesterday ?

**Solution : **

To find the number of books in the library day before yesterday, subtract 76 from 1028.

= 1028 - 76

= 952

So, there would have been 952 books in the library day before yesterday.

**Problem 3 : **

In a drawing competition, 825 students took part and 423 among them were girls. How many boys took part in the competition ?

**Solution : **

To find the number of boys, subtract 423 from 825.

= 825 - 423

= 402

So, 402 boys took part in the competition.

**Problem 4 : **

The temperature at 5 P.M. was 28°F. At 11 P.M, it had dropped 40°F. What was the temperature at midnight ?

**Solution : **

Visualize a number line. The drop from 28° to 0° is 28°. There are still 12 more degrees to drop. They will be below zero. -12°F is the temperature at 11 P.M.

**Problem 5 : **

Jonathan scored 632 marks and received grade A in an examination, Clark scored 75 marks less than Jonathan and received grade B in the same examination. Find the marks scored score Clark.

**Solution : **

To find the marks scored by Clark, subtract 75 from 632.

= 632 - 75

= 557

So, Clark scored 557 marks.

**Problem 6 : **

Peterson sold 1257 meatballs on Sunday. He sold 158 less more meatballs on Monday than on Saturday. How many meatballs did he sell on Monday ?

**Solution : **

Number of meatballs sold on Sunday :

= 1257

Given : On Monday, 158 less meatballs sold than on Sunday.

Then, number of meatballs sold on Monday :

= 1257 - 158

= 1099

So, Peterson sold 1099 meatballs on Monday.

**Problem 7 : **

Distance from place X to Z is 183 miles, distance from place Y to place Z is two-third of the distance from place X to place Z. If Y is between X and Z, find the distance from place X to place Y.

**Solution : **

Distance from place X to place Z :

= 183 miles

Distance from place Y to place Z :

= 2/3 ⋅ (Distance from X to Z)

= 2/3 ⋅ 183 miles

= 122 miles

Distance from place X to place Y :

= (Distance from X to Z) - (Distance from Y to Z)

= 183 - 122

= 61 miles

So, the distance from Place X to place Y is 61 miles.

**Problem 8 : **

In a running race, Kevin reached the target in 2 minutes 5 seconds and lost the first price by 12 seconds. In what time should he have completed the race to get the first price ?

**Solution : **

Actual time taken by Kevin to complete the race :

= 2 min 5 sec

= 120 sec + 5 sec

= 125 seconds

Given : Kevin lost the first price by 12 seconds.

Then, to find the time required to get the first price, subtract 12 from 125.

= 125 - 12

= 113 seconds

So, Kevin should have completed the race in 113 seconds to get the first price.
