There are 15 apples in 3 boxes.

Number of apples in 1 box :

= 15/3

= 5

Number of apples 7 boxes :

= 7 x 5

= 35

Problem 4 :

If there are 17 kilograms of a chemical powder in 5 bags, how many kilograms of the same chemical powder will be in 35 bags?

Solution :

There are 17 kilograms of powder in 5 bags.

5 bags ----> 17 kilograms

7(5 bags) ----> 7(17 kilograms)

Problem 5 :

Mr. A divides $3600 equally into three parts. He keeps one pat for himself, one part for a charity and one part is divided equally among his three sons. Find the share of each son.

Solution :

$3600 is equally divided into three parts.

The value of each part :

= 3600/3

= $1200

Now, $1200 is divided equally among three sons.

The share of each son :

= 1200/3

= $400

Problem 6 :

A month before, Mr. James divided $2800 equally into two parts. He invested one of the parts in stock A and other in stock B. Now, investment in stock A is doubled and investment in stock B became half of it. Find the total value of both the investments now. 

Solution :

$2800 is divided equally into two parts.

The value of each part :

= 2800/2

= $1400

Total values of both the investments now :

= 2(1400) + (1/2)(2500)

= 2800 + 0.5(2500)

= 2800 + 1250

= $4050

Problem 7 :

Mr. Richard buys five pizzas for the students in his class. There are 20 students in the class  and each pizza has 8 slices. If each student gets equal amount pf pizza, find the number of slices each student gets.

So, 40 slices have to divided among 20 students.

Number of slices each student gets :

= 40/20

= 2

Problem 8 :

Ben walks around a circular yard. If it takes him 15 minutes to completely walk 1 time around, find the number of rounds he ill complete in 2 hours 30 minutes.

Solution :

15 minutes ----> 1 round

2(15 minutes) ----> 2(1 round)

30 minutes ----> 2 rounds

2(30 minutes) ----> 2(2 rounds)

60 minutes ----> 4 rounds

1 hour ----> 4 rounds

2(1 hour) ----> 2(4 rounds)

2 hours ----> 8 rounds

Number of rounds Ben will complete in 2 hours 30 minutes :

= 2 + 8

= 10

Problem 9 :

Lily divides 5 boxes of cookies equally among her 4 kids and each kid gets 25 cookies. Find the number of cookies in each box.

Solution :

1 kid ----> 25 cookies

4(1 kid) ----> 4(25 cookies)

So, there are 100 cookies in 5 boxes.

Number of cookies in each box :

= 100/5

= 20

Problem 10 :

A person does 8 units of work in a day. If 7 people work for 13 days, find the number of units of work completed.

Solution :

Number of units of work completed by 1 person in 1 day :

= 8

Number of units of work completed by 7 people in 1 day :

= 7 x 8

= 56

Number of units of work completed by 7 people in 13 day :

= 13 x 56

= 728

Problem 11 :

15 people complete 750 units of work in 10 days. On average, how many units of work does one person complete  in one day?

Solution :

Number of units of work completed by 15 people in 10 days :

= 750

Number of units of work completed by 15 people in 1 day :

= 75

Number of units of work completed by 1 person in 1 day :

= 75/15

= 5

Problem 12 :

A jeweler can make 80 ounces of gold ornaments per day. If 100 lbs. gold ornaments are to be made in 5 days, how many jewelers are required?

1 lb. = 16 ounces

100(1 lb.) = 100(16 ounces)

100 lbs. = 1600 ounces

1600 ounces of ornaments have to be made in 5 days.

1 jeweler in 1 day ----> 80 ounces

1 jeweler in 5 days ----> 5(80 ounces)

1 jeweler in 5 days ----> 400 ounces

Number of jewelers required to make 1600 ounces (1 lbs.) of ornaments in 5 days :

= 1600/400

= 4
