Answer 1

L the cost price of a type writer is Rs.X

Loss = 5 %

Then, the selling price of typewriter = X×95100

= 19X20

Gain = 5 %

Then the selling price = X×105100

= 21X20

Then,

21X20–19X20=80

(21X–20X)20=80

X=80×20

X=Rs.1600

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

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

At 5% loss. SP = Rs. 95x/100

Now, 95x/100 + 80 = 105x/100

=> 105x/100 − 95x/100 = 80

=> 105x − 95x/100 = 80

=> x = 8000/10 =Rs.800

Ans :- The cost price of typewriter is RS. 8000
