**Time and Work**

**Answers:**

1.

Total investment = Rs. (7200+200+ 600) Rs. 8000.

Total receipt Rs. (330 x 28) = Rs. 9240.

profit % = [1240/8000] * 100 = 15.5

2.

Suppose he bought 5 kg and 3 kg of tea.

Cost Price = Rs. (5 x 18 + 3 x 20) = Rs. 150.

Sell price = Rs. (8 x 21) = Rs. 168.

profit % = (18/150) * 100 = 12%

3

Let the cost price of 1 article be $1.

Therefore, cost price of 20 articles = 20 * 1 = $20

The selling price of 25 articles = cost price of 20 articles = $20.

Now, we know the selling price of 25 articles. Let us find the cost price of 25 articles.

Cost price of 25 articles = 25 * 1 = $25.

Therefore, profit made on sale of 25 articles = Selling price of 25 articles - cost price of 25 articles

= 20 - 25 = -$5.

As the profit is in the negative, the merchant has made a loss of $5.

Therefore, % loss = loss/cp * 100

% loss = -5/25 * 100 = 20% loss.

4.

Total CP = (12*4 + 16 *2) = 80

SP of 6 dozen oranges = [(120/100 )* 80)] = 96

sell price per dozen =16

5.

110% of 9O% of 120% of A = 1188.

[(110/100)*(90/100)*(120/100)*A] = 1188 or A = 1188/1000

since A =1188 hence A = 100

A purchased it for Rs. (1000— 110) = Rs. 890.

6.

rate of buying = 7; rate of selling = 10 to gain 3 Rs he must buy 1 kg

for 102 profit he must buy = (102/3) = 34

7.

Total investment = Rs. (120 * 80 + 280 + (40/100) * 120 + 72).

= Rs. (9600 + 280+48 + 72) = Rs, 10000.

Sell price of 120 reams = 108% of Rs. 10000 = Rs. 10800.

Sell Price per ream = Rs. [10800/120] = Rs. 90.

8.

Cost price of 25 kg = Rs. (15 x 14.50 + lOx 13) = Rs. 347.50.

Sell price of 25 kg = Rs. (25 x 15) = Rs. 375.

profit = Rs. (375 — 347.50) = Rs. 27.50.

9.

Total S.P. Rs, 24000.

C.P. of horse =Rs. [(100/80) x 12000] = 15000.

C.P. of cow = Rs.[(100/120) x 12000] = 10000

Total C.P. = Rs. 25000.

Loss = Rs. (25000—24000) Rs 1000.

10.

Let S.P. of 45 lemons is Rs. x.

80 : 40 = 120 : x or 80/40 = 120/x or x = 40 * 120 / 80 = 60

lemons sold For Rs. 60, = 45

lemons sold For Rs. 24, = (45/60) * 24= 18.

**(a)**Total investment = Rs. (7200+200+ 600) Rs. 8000.

Total receipt Rs. (330 x 28) = Rs. 9240.

profit % = [1240/8000] * 100 = 15.5

2.

**(c)**Suppose he bought 5 kg and 3 kg of tea.

Cost Price = Rs. (5 x 18 + 3 x 20) = Rs. 150.

Sell price = Rs. (8 x 21) = Rs. 168.

profit % = (18/150) * 100 = 12%

3

**.(c)**Let the cost price of 1 article be $1.

Therefore, cost price of 20 articles = 20 * 1 = $20

The selling price of 25 articles = cost price of 20 articles = $20.

Now, we know the selling price of 25 articles. Let us find the cost price of 25 articles.

Cost price of 25 articles = 25 * 1 = $25.

Therefore, profit made on sale of 25 articles = Selling price of 25 articles - cost price of 25 articles

= 20 - 25 = -$5.

As the profit is in the negative, the merchant has made a loss of $5.

Therefore, % loss = loss/cp * 100

% loss = -5/25 * 100 = 20% loss.

4.

**(c)**Total CP = (12*4 + 16 *2) = 80

SP of 6 dozen oranges = [(120/100 )* 80)] = 96

sell price per dozen =16

5.

**(c)**110% of 9O% of 120% of A = 1188.

[(110/100)*(90/100)*(120/100)*A] = 1188 or A = 1188/1000

since A =1188 hence A = 100

A purchased it for Rs. (1000— 110) = Rs. 890.

6.

**(b)**rate of buying = 7; rate of selling = 10 to gain 3 Rs he must buy 1 kg

for 102 profit he must buy = (102/3) = 34

7.

**(a)**Total investment = Rs. (120 * 80 + 280 + (40/100) * 120 + 72).

= Rs. (9600 + 280+48 + 72) = Rs, 10000.

Sell price of 120 reams = 108% of Rs. 10000 = Rs. 10800.

Sell Price per ream = Rs. [10800/120] = Rs. 90.

8.

**(d)**Cost price of 25 kg = Rs. (15 x 14.50 + lOx 13) = Rs. 347.50.

Sell price of 25 kg = Rs. (25 x 15) = Rs. 375.

profit = Rs. (375 — 347.50) = Rs. 27.50.

9.

**(c)**Total S.P. Rs, 24000.

C.P. of horse =Rs. [(100/80) x 12000] = 15000.

C.P. of cow = Rs.[(100/120) x 12000] = 10000

Total C.P. = Rs. 25000.

Loss = Rs. (25000—24000) Rs 1000.

10.

**(c)**Let S.P. of 45 lemons is Rs. x.

80 : 40 = 120 : x or 80/40 = 120/x or x = 40 * 120 / 80 = 60

lemons sold For Rs. 60, = 45

lemons sold For Rs. 24, = (45/60) * 24= 18.
