    A) Rs. 704

    B)  Rs. 640  

    C)  Rs. 774

    D)  Rs. 680 

    Correct Answer: B

    Solution :

      SP of article\[\,=(100-20)%\]of 880 = 80% of 880 \[=880\times \frac{80}{100}\]= Rs. 704 Again, 110% = 704 \[100%=\frac{704}{110}\times 100\]= Rs. 640 \[\therefore \] Original cost = Rs. 640
