A
Total Cost Price = Rs 5000 . Total profit = 10% . Total Selling Price =1.1×5000=5500
Now go from answer options
If the number of footballs sold at profit is 25, then revenue for these 25 balls =1.3×25×100=3250
And the number of footballs sold at loss will be 25; revenue for these balls =0.9×25×100=2250
Sum= 5500 = 10% profit on 5000
Thus, the assumption is right
