I. If the cost of 12 apples is Rs 200. what is the cost of 18 apples?

Solution:

Given,
The cost of 12 apples=Rs 200
Let the Cost of 18 apples be x.
By the proportion, we get
200/12=x/18
18.200=12x
3600=12x
x=3600/12=300
Therefore, the cost of 18 apples is Rs 300.

II. The ratio of gold and copper, in an alloy is 5: 3. If the weight of gold, in the alloy is 2 kg; find the weight of the copper in the alloy?

Solution:

Given,
The ratio of gold and copper, in an alloy, is =5: 3
Weight of the gold=2 kg
Let the Weight of the copper=3x
weight of the gold=5x
2=5x
x=2/5=0.4
Weight of the copper in the alloy=3x
=3(0.4)=1.2 kg
Therefore, the ratio of copper in the alloy is 1.2 kg.

III. A worker working at the company earns Rs 1000 for every 9 hours of work. How much will the worker earn in 34 hours?

Solution:

Given,
No. of hours of work=9
He earns money for 9 hours=Rs 1000
Let the worker earn be x working for 34 hours.
By applying the proportion we get
1000/9=x/34
34000=9x
x=34000/9
=3777
Therefore, The worker will get Rs 3777 for working 34 hours.

IV. The first, second, and fourth terms of a proportion are 4, 5, and 10, respectively. Find its third term.

Solution:

Let the third term be x.
By applying the proportion we get
4:5=x:10
4.10=5. x
5x=40
x=40/5=8
Therefore, the third term is 8.

V. A map is given with a scale of 2 cm=400 km. What is the actual distance between the two places in km. If the distance in the map is 3.5 cm?

Solution:

Given that,
A scale of 2 cm=400 km
Let the scale of 3.5 cm be x.
By using the proportion we get
400:2=x:3.5
400.3.5=2x
x=400.3.5/2
=700 km
Therefore, the actual distance between the two places is 700 km.

VI. The ratio of the sale of Dresses on a Sunday to that of the whole week of the shop was 4: 9. If the total sale of dresses in the same week was Rs 5000, find the sale of dresses on Sunday?

Solution:

Given that,
The ratio of the sale of Dresses on a Sunday to that of the whole week of the shop was =4: 9
Let the sales of dresses on a Sunday=4x
Let the sales of dresses of the whole week=9x
The total sale of dresses in the same week was=Rs 5000
9x=5000
x=5000/9=555.55
Sales of dresses on the Sunday=4x=4(555.55)=2222
Hence, the Sales of dresses on a Sunday is Rs 2222.

VII. A picture measuring 5” high by 7” wide is to be enlarged so that the width is now 9. How tall will the picture be?

Solution:

Given that,
The height of the picture=5
The width of the picture=7
After enlarging the width is=9
Let the height of the picture=h
5/7=h/9
45=7h
h=45/7=6.42
Therefore, the height of the picture is 6.42.

VIII. In a mixture of 65 liters, the ratio of water to milk is 1:2. What is the amount of water to be added if the ratio has to be 2:1?

Solution:

Given that,
The ratio of water and milk=1:2
Number of litres of water = (1/(1+2)) *65 = 21 litres.
So, 65-21= 44 liters of milk is present in it.
Let the quantity of water to be added be x liters.
Setting up the proportion,
water /milk= (21+x)/44 = 2/1
21+x=88
x=67.
Therefore, 67 liters of water have to be added to bring it to the ratio of 2:1.

IX. A certain recipe calls for 2 kgs of sugar for every 4 kgs of flour. If 80kgs of this sweet has to be prepared, how much sugar is required?

Solution

:
Let the quantity of sugar required to be x kgs.
2 kgs of sugar added to 4 kgs of flour constitutes a total of 6 kgs of sweet.
2 kgs of sugar is present in 6 kgs of sweet. We need to find the quantity of sugar required for 80 kgs of sweet. So the proportion looks like this.
2/6 = x/80
160=6x
x=26.
Therefore, 26 kg of sugar is required for 60 kgs of sweet.

X. If 50 ml of water contains 14% of chlorine, how much water must be added in order to create an 8% chlorine solution?

Solution:

Let x ml of chlorine be present in water.
By applying the proportion we get,
Then, 14/100 = x/50
x = 7 ml
Therefore, 7 ml is present in 50 ml of water.
In order for this 7 ml to constitute 8% of the solution, we need to add extra water. Let this be y ml.
Then, 8/100 = 7/y → y =87.5 ml.
So in order to get an 8% chlorine solution, we need to add 87.5-50 = 37.5 ml of water.

XI. At a birthday party for 120 people, it was estimated that one bottle of cool drink would be sufficient for 5 people. How many bottles would be sufficient for 120 people?

Solution:

Given that,
Total no. of people at the birthday party=120
one bottle of cool drink will be sufficient for the people=5
Let x bottles be sufficient for 120 people.
By the proportion we get,
1:5=x:120
120=5x
x=120/5=24
Therefore, 24 bottles are sufficient for 120 people.

XII. Sameera used 6 packets of bread on an 8-day hiking trip. How many packets of bread she should pack for a 12-day hiking trip if she eats the same amount of bread each day?

Solution:

Given that,
6 packets of bread are sufficient for the 8-day hiking trip.
Let b packets are sufficient for a 12-day hiking trip.
By using proportion,
b/12=6/8
b/12=3/4
b=3/4.12
=9
Therefore, Sameera should pack 9 packets of bread for the 12-day hiking trip.
