Math : Grade 5 : Exercise 2C

1. Find the selling price or cost price of each of these products with the help of a model.

a. Terracota pot from west bengal.
Cost price = Rs 315
Loss = Rs 38
Selling Price=?

here, given Loss and cost price
We know that,  Loss = Cost Price - Selling Price
here, we have to find Selling Price
hence Selling Price = Cost Price - Loss
lets substitute the given values
Selling Price = Rs 315 - Rs 38
                      = Rs 277

b. Stool from Punjab.
Selling Price = Rs 690
Loss = Rs 57
Cost Price = ?

Cost Price = Loss + Selling Price
Cost Price = Rs 57 + Rs 690
                  = Rs 747

c. Shawl from Nagaland.
Selling Price = Rs 1,560
Loss = Rs 350
Cost Price = ?

Cost Price = Loss + Selling Price
Cost Price = Rs 350 + Rs 1,560
                  = Rs 1,910

d. Kanjeevaram saree from Tamil Nadu.
Cost Price = Rs 7,880
Profit = Rs 1,090
Selling Price = ?

Profit = Selling Price - Cost Price
Selling Price = Profit + Cost Price
                      = Rs 1,090 + Rs 7,880
                      = Rs 8,970

2. Complete the table.


Selling Price
Profit
Loss
Cost Price
a
Rs 2,385
Rs 195
-
Rs 2,385 - Rs 195 = Rs 2,190
b
Rs 1,900
-
Rs 628
Rs 1,900 + Rs 628 = Rs 2,528
c
Rs 8,630
-
Rs 1,020
Rs 8,630 + Rs 1,020 = Rs 9,650
d
Rs 74,365
Rs 2,315
-
Rs 74,365 - Rs 2,315 = Rs 72,050

 

Note : Cost Price = Loss + Selling Price , Cost Price = Selling Price - Profit.         

3. Complete the table.


Cost Price
Profit
Loss
Selling Price
a
Rs 1,095
-
Rs 89
Rs 1,095 - Rs 89 = Rs 1,006
b
Rs 3,586
Rs 369
-
Rs 3,586 + Rs 369 = Rs 3,955
c
Rs 9,980
-
Rs 3551
Rs 9,980- Rs 3551 = Rs 6,429
d
Rs 15,381
Rs 1,395
-
Rs 15,381 + Rs 1,395 = Rs 16,776
 

Note : Selling Price = Cost Price + Profit , Selling Price = Cost Price - Loss.

4. Solve

a. Rashid incurred a loss of Rs 590 on a chair he sold at Rs 1,280. What was the cost price of the chair?

Given, Loss = Rs 590 and selling price = Rs 1,280
Cost Price = Selling Price + Loss
                 = Rs 1,280 + Rs 590
                 = Rs 1,870

b. Ali made a profit of Rs 3,200 on a sofa set he bought for Rs 15,290. At what price did he sell it?

Given, Profit = Rs 3,200 and cost price = Rs 15,290
Selling Price = Cost Price + Profit
                     = Rs 15,290 + Rs 3,200
                     = Rs 18,490

c. A dozen books are sold at Rs 1,648 at a profit of Rs 120. What is the cost price of the books?

Given, profit = Rs 120 and Selling Price = Rs 1,648
Cost Price = Selling Price - Profit
                 = Rs 1,648 - Rs 120
                 = Rs 1,528
