On selling 17 balls at Rs. 720, there is a loss equal to the cost price of 5 balls. The cost price of a ball is:
Answer: Option
Explanation:
(C.P. of 17 balls) - (S.P. of 17 balls) = (C.P. of 5 balls)
C.P. of 12 balls = S.P. of 17 balls = Rs.720.
| C.P. of 1 ball = Rs. |
 |
720 |  |
= Rs. 60. |
| 12 |

Cost of 1 ball = x.
Cost of 17 ball = 17x.
Selling price of 17 ball = 720.
Loss = 5x where x is price of 1 ball.
Loss = cp - sp.
5x = 17x - 720.
x = 60.
Cost of 17 ball = 17x.
Selling price of 17 ball = 720.
Loss = 5x where x is price of 1 ball.
Loss = cp - sp.
5x = 17x - 720.
x = 60.

@Murali.
You are incorrect.
As acc to you.
Given in the problem.
5x/17 = x-720/17.
But actual is.
5x/17 = x/17-720/17.
Now you will get incorrect answer.

Simply we can say that;
CP for 1 ball=x,
CP for 17 ball=17x,
SP for 17 ball=720.
Loss= CP - SP.
5x(overall)=17x-720,
X=60 price for each ball.
CP for 1 ball=x,
CP for 17 ball=17x,
SP for 17 ball=720.
Loss= CP - SP.
5x(overall)=17x-720,
X=60 price for each ball.

cp of 17 balls = 720 + cp of 5 balls,
cp of 17 balls - cp of 5 balls = 720,
cp of 12 balls = 720,
cp of 1 ball = 720/12,
So, cp of 1 ball = 60.
cp of 17 balls - cp of 5 balls = 720,
cp of 12 balls = 720,
cp of 1 ball = 720/12,
So, cp of 1 ball = 60.

(C.P. of 17 balls) - (S.P. of 17 balls) = (C.P. of 5 balls)
C.P. of 12 balls = S.P. of 17 balls = Rs.720.
C.P. of 1 ball = Rs. 720/12 = Rs. 60.
C.P. of 12 balls = S.P. of 17 balls = Rs.720.
C.P. of 1 ball = Rs. 720/12 = Rs. 60.

loss% = cp - sp/cp.
15/100= (x-18700)/x.
15x = 100x-1870000.
x(cp)=22000.
Again have to gain profit 15%.
sp=22000*115%.
====> 25300.
15/100= (x-18700)/x.
15x = 100x-1870000.
x(cp)=22000.
Again have to gain profit 15%.
sp=22000*115%.
====> 25300.

Consider CP of 1 ball is X.
For 17 balls, CP is 17X.
Loss = CP-SP.
i.e;17X - 720.
Loss = 5X.
5X = 17X-720,
12X = 720,
X = 60.
For 17 balls, CP is 17X.
Loss = CP-SP.
i.e;17X - 720.
Loss = 5X.
5X = 17X-720,
12X = 720,
X = 60.

SP = CP*(loss)or(gain)%.
SP = 720;
CP = x;
loss = 5 of CP = 5 (x);
720 = x*5x;
5x*x = 720;
x^2 = 144;
x = 12;
720/12 = 60.
SP = 720;
CP = x;
loss = 5 of CP = 5 (x);
720 = x*5x;
5x*x = 720;
x^2 = 144;
x = 12;
720/12 = 60.

SP of 17 balls will be subtracted CP of 5 balls. Because there is a loss equal to 5 balls in selling of 17 balls.

SP of 17 balls = Rs.720.
CP 1 ball = x,
CP 17 balls = 17x.
CP - SP = loss.
17x - 720 = 5x.
12x = 720.
x = 60.
CP 1 ball = x,
CP 17 balls = 17x.
CP - SP = loss.
17x - 720 = 5x.
12x = 720.
x = 60.
