Answer: (3) 37.5 %

Explanation:-
The selling price of an item = Rs.640
Loss = 20 %

Then, the cost price of an item = 640 x 100/80
= Rs.800

If, hr makes profit 10 %,
Then, the selling  price of an item = 800 x 110/100
= Rs.880
Increased the selling price = 880 – 640
= Rs.240

Percentage of increase  selling price = 240  x 100/640
= 24 x 100 /64
= 3 x 100/8
= 3 x 25 /2
=  37.5 %

Hence, the answer is (3) 37.5%.
