By selling two bicycles,a dealer neither earns profit nor earn loss.if...
Let the cost of the bicycle with 9% loss be x.
Then the cost of another bicycle with 15 % profit will be (4320 - x).
Given that,
15% of (4320 - x) = 9% of x
= 15/100 × (4320 - x) = 9/100 × x (Cancel out 100 on both sides and cancel out 15 and 9 by coommon factor 3)
= 5 × 4320 - 5x = 3x
= 5 × 4320 = 3x + 5x
= 5 × 4320 = 8x
= x = ( 5 × 4320 ) / 8
= 5 × 540
= 2700
x = 2700
Now if the cost of 1 bicycle is Rs. 2700 the cost of another bicycle will be,
4320 - 2700 = 1620
Therefore , the cost of another bicycle is Rs. 1620
Check the answer :
15% of 1620 = 9% of 2700
= 15/100 × 1620 = 9/100 × 2700
= 243 = 243
Therefore , the answer is correct....

By selling two bicycles,a dealer neither earns profit nor earn loss.if...
Given information:
- The dealer sells two bicycles.
- The dealer neither earns a profit nor incurs a loss.
- One bicycle is sold at a 15% profit.
- The other bicycle is sold at a 9% loss.
- The cost price of both bicycles combined is Rs 4320.
To find:
- The cost price of each bicycle.
Solution:
Let's assume the cost price of the first bicycle is x and the cost price of the second bicycle is y.
Equations:
1. Selling price of the first bicycle = Cost price of the first bicycle + 15% profit
2. Selling price of the second bicycle = Cost price of the second bicycle - 9% loss
3. Cost price of both bicycles = x + y = Rs 4320
Calculating the selling prices:
- Selling price of the first bicycle = x + (15/100)x = 1.15x
- Selling price of the second bicycle = y - (9/100)y = 0.91y
Since the dealer neither earns a profit nor incurs a loss, the total selling price should be equal to the total cost price.
Equation:
1.15x + 0.91y = x + y
Rearranging the equation:
0.15x - 0.09y = 0
Simplifying further:
15x - 9y = 0
We also know that x + y = 4320. We can solve these two equations simultaneously to find the values of x and y.
Solving the equations:
1. 15x - 9y = 0
2. x + y = 4320
Multiplying equation 2 by 9 and subtracting it from equation 1:
15x - 9y - (9x + 9y) = 0 - 38880
6x = -38880
Dividing both sides by 6:
x = -38880/6
x = -6480
Substituting the value of x in the equation x + y = 4320:
-6480 + y = 4320
y = 4320 + 6480
y = 10800
Therefore, the cost price of the first bicycle is Rs 6480 and the cost price of the second bicycle is Rs 10800.
Conclusion:
The cost price of the first bicycle is Rs 6480 and the cost price of the second bicycle is Rs 10800.
- The dealer sells two bicycles.
- The dealer neither earns a profit nor incurs a loss.
- One bicycle is sold at a 15% profit.
- The other bicycle is sold at a 9% loss.

y = 10800

Conclusion:
The cost price of the first bicycle is Rs 6480 and the cost price of the second bicycle is Rs 10800.
