Given:
Niruta sold two washing machines for Rs.9900 each.He sold one at a gain of 10% & other at a loss of 10%.
Find:
Profit or Loss..
Solution:
Selling price of first washing machine, (S.P) = Rs.9900
Gain on washing machine = 10%
C.P = ?
Using formula of the cost price when become profit;
So,
Selling price of second washing machine, (S.P) = Rs.9900
Loss on washing machine = 10%
C.P = ?
Using formula of the cost price when become loss;
So,
Now,
Total selling price of both washing machine = Rs.9900 + Rs.9900 = Rs.19800 .
Total cost price of both washing machine = Rs.9000 + Rs.11000 = Rs.20000 .
S.P < C.P
→ Loss = Cost price - Selling price
→ Loss = Rs.20000 - Rs.19800
→ Loss = Rs.200
As we know that formula of the loss% ;
→ Loss % = 200 × 100/20000
→ Loss % = 20000/20000
→ Loss % = 1%
Thus,
The whole transaction of loss% will be 1% .
