Answer is wrong (Question: 152020.0 )

Correct answer is 450.From where you got 7680 ??? Dont mislead students.I am frequently seeing mistakes in your tests.Also admin is answering things without logic.Please put some one good in maths as admin.As of your current standard, students may loose scoring maths in exams .

Question:
A dealer sold two watches for Rs.3,600 each, gaining 25% on one and losing 25% on another. How much he gain or loss in the whole transaction?
Options:
A) 460
B) 470
C) 480
D) None of these 
Solution:

Ans: (c) 

SP of first watch = Rs. 3600, gain = 25% 
CP of first watch = (100/125) x 3600 = Rs. 2880
SP of second watch = Rs. 3600, loss = 25%
CP of second watch = (100/75) x 3600 = Rs. 4800
Total CP = (2880 + 4800) = 7680 
Total SP = (3600 x 2) = Rs. 7200
Loss = (7680 - 7200) = Rs. 480
So, on the whole, there is a loss of Rs. 480

Dear student,
Given answer is correct
According to Solution
We find the Loss% is = 6.25%
Total SP is 7200
CP = (SP x 100) / (100 - loss)
CP = 7680
loss = 7680 x 6.25%
= 480
