A man sells his typewriter at 5% loss. Ifhe sells it for Rs. 80 more, he gain 5%. The cost price of typewriter is:

- Rs. 1600
- Rs. 1200
- Rs. 1000
- Rs. 800

**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.
