Question

a milkman sold two buffaloes for rs20000 each on one he made again of 5% on the other a loss of 10% . Find his ourrall gain or loss​

Answer 1

Given:

• SP of each Buffaloes = Rs. 20000
• Gain= 5% on one and loss of 10% on the other.

To find:

• Overall Gain Or Loss

Solution:

Now,

• SP. of buffaloe (1) = Rs. 20,000
• Gain= 5%
• $∴Cp = \frac{100}{105} \times 2000 = Rs. 19047.62$
• SP. of buffaloes (2) = Rs. 20,000
• Loss= 10%
• ∴Cp(2)=100/90×20,000
• =Rs. 22,222.22
• Total Cp= Cp(1)+Cp(2)
• =Rs. 41269.84
• Total Sp=20,000+20,000
• =Rs. 40,000
• ∴Loss= Cp-SP
• = (41269.84- 40,000)
• =Rs. 1269.84
• Hence, the loss is Rs. 1269.84

Answer 2

Answer:

Given,

Selling price of Buffaloes = 20000 each.

Total selling price = 2 * Selling price of 1 Buffalo

= 2 * 20000

= 40000

Total Cost Price

= Cost price of first Buffalo + Cost price of second buffalo. ..... (I)

Cost price of first Buffalo

Selling price =20000

Gain percentage = 5%

Let the cost price be x

We know that,

Gain = Selling price - Cost price

Gain = 20000 - x

Also gain percentage

= Gain / cost price * 100

5 = 20000 - x / x * 100

5x = ( 20000-x) * 100

5x = 200000 - 100x

5x + 100x = 200000

105x = 2000000

x = 2000000/105

Cost price of first Buffalo = 20000

Gain percentage = 5%

Let the cost price be x

We know that,

Gain = Selling price - Cost price

Gain = 20000 - x

Also,

Gain percentage

Gain /Cost price * 100

5 = 20000 - x / x *100

5x = 200000 - 100x

5x + 100x = 200000

105x = 2000000

x = 2000000/105

Cost price of second Buffalo

SP = 20000

Loss percentage =10%

Let the cost price = y

We know that

Lose = CP - SP

Also,

Loss percentage

= loss / cost price * 100

10 = y- 20000/y * 100

10 y = y- 20000 *100

10 y = 100y -2000000

10y - 100y = 2000000

-90 y = -2000000

y = 2000000/90

therefore, cost price of first Buffalo = 2000000/105

Cost price of second Buffalo= 2000000/90

putting values in equation (1 )

Total CP = Cost price of first Buffalo + cost price of second Buffalo

= 2000000/105 + 2000000/90

= 2000000[ 1/90 + 1/105]

= 2000000[105+90/105*9]

= 2000000[195/105 *9]

= 2600000/63

= 41269.83

Hence, SP = 40,000 and CP = 41,269.83

Since CP >SP

He made a loss

Loss = CP - SP

41,269.83 - 40,000

= 1269.83

Therefore, he overall loss of Rs. 1269.83
