**Question 1:**

**If the manufacturer gains 15%, the wholesale dealer gets 20% and the retailer gets 30%, then find the cost of production of a blackboard, the retail price of which is $ 1360?**

Solution:

Cost of production of blackboard be ‘X’

115% of 120% of 130% of cost price is

i.e. \(\frac { 115 }{ 120 } \)*\(\frac { 120 }{ 100 } \)*\(\frac { 130}{ 100} \)*1360

Cost of production of a blackboard $ 758.08

**Question 2:**

A man bought a dog and a kennel for $ 4500. He sold the dog at a gain of 25% and the carriage at a loss of 15%, thereby gaining 3% on the whole. Find the cost of the dog.

Solution:

Cost price (C.P.) of dog ‘X’

Cost price (C.P.) of kennel ‘4500 – X’

25% of x – 15% of (4500 – X) = 3% of 4500

Cost of a dog is $ 1373.68.

**Question 3:**

**Profit earned by selling television for $ 6000 is 25% more than the loss incurred by selling the article for $ 4500. At what price should the article be sold to earn 25% profit?**

Solution:

let cost price (C.P.) be ‘X’

By equalizing,

(6000 – X) = \(\frac { 125 }{ 100 } \)*(X-4500)

Desired selling price of the television is $ 6458.3.

**Question 4:**

**A manufacturer undertakes to supply 2200 pieces of a particular component at $ 30 per piece. According to his estimates, even if 6% fail to pass the quality tests, then he will make a profit of 30%. However, as it turned out, 60% of the components were rejected. What is the loss to the manufacturer?**

Solution:

Incurred cost = $(\(\frac { 100 }{ 130 } \)*30*(94% of 2200))

Loss = C.P. – S.P.

The loss to the manufacturer is $ 8123.07.

**Question 5:**

**John bought a lorry for a certain sum of money. He spent 15% of the cost on repairs and sold the lorry for a profit of $ 1600. How did he spend on repairs if he made a profit of 30%?**

Solution:

Let the Cost price (C.P.) of the lorry be ‘X’

Profit (P) = $16,00

Profit (%) = 30

Profit (%) = \(\frac { 100 }{ CP } \)*P

30 = \(\frac { 100 }{ CP} \)*1600

CP = \(\frac { 100 }{ CP} \)*1600

CP = \(\frac { 100 }{ 30} \)*1600

= $5333.3

The C.P Includes both original price and repairs cost

C.P +0.15C.P = $5333.3

1.15 C.P = $5333.3

C.P = $4637.68

Repairs Cost = Total Cost Price – Cost Price for which john bought the lorry

= $5333.3 – $4637.68

= $ 695.61

Expenditure spend on repairs = $ 695.61.

**Question 6:**

**A boy bought 25 litres of milk at the rate of $ 12 per litre. He got it churned after spending $ 15 and 7kg of cream and 25 lit of toned milk were obtained. If he sold the cream at $ 40 per kg and toned milk at $ 6 per lit, what is his profit % in the transaction?**

Solution:

Cost price (C.P.) = $ ((25*12) + 15)

Selling price (S.P.) = $ ((7*40) + (25*6))

Gained profit % on the above transaction is 36.50%.

**Question 7:**

**Arun purchased 150 reams of paper at $ 90 per ream. He spent $ 300 on transportation, paid local tax at the rate of 50 paise per ream, and paid $ 76 to coolie. If he wants to have a gain of 10%, what must be the selling price per ream?**

Solution:

Total investment = $ (((150*90) + 300) + ((50/100 * 150) + 76))

Find selling price per ream

Selling price per ream = $ 102.3

**Question 8:**

**A retailer mixes three varieties of dal costing $ 50, $ 25, and $ 30 per kg in the ratio 3: 5: 2 in terms of weight, and sells the mixture at $ 35 per kg. What percentage of profit does he make?**

Solution:

Cost price (C.P.) of dal for 10 kgs = $ ((3*50) + (5*25) + (2*30))

Selling price for 10 kgs = $ (10*35)

Profit percentage on transactions is 4.74%.

**Question 9:**

**A man buys chocolates at 3 for $ 2 and an equal number at 5 for $ 3 and sells the whole at 6 for $ 4. His gain or loss percent is?**

Solution:

Suppose he buys 7 eggs of each kind

Find C.P. and S.P. for 14 eggs

C.P. = $ ((\(\frac { 2 }{ 3 } \) * 7) + (\(\frac { 3 }{ 5 } \) * 7)) = $ 8.86

Similarly, find S.P.

The gain % obtain is 5.34%.

**Question 10:**

The manufacturer of a certain item can sell all he can produce at the selling price of $ 65 each. It costs him $ 45 in material and labor to produce each item and he has overhead expenses of $ 3500 per week in order to operate the plant. The number of units he should produce and sell in order to make a profit of at least $ 1200 per week is?

Solution:

Consider he produces ‘x’ items

Cost price (C.P.) = $ (45x + 3500)

Selling price (S.P.) = $ 65x

The number of units produced per week to gain profit is 235.
