Answer: (1) Rs.1600

Explanation:-
L the cost price of a type writer is Rs.X
Loss = 5 %

Then, the selling price of typewriter = X x 95/100
= 19 X / 20

Gain = 5 %
Then the selling price = X x 105/100
= 21 X / 20

Then,  21 X / 20 – 19 X/20 = 80
( 21 X –  20 X ) / 20 = 80
X = 80 x 20
X = Rs.1600

Then, the cost price of a typewriter is Rs.1600

Hence, the answer is (1) Rs.1600.
