Question

6. A man sold a transistor for 450 at a loss of 10%. Find the cost price of the transistor - (A) = 400 (B) 500 (C) 110 (D) 490​

Answer 1

Answer:

The cost of transistor is (B) 500.

Step-by-step explanation:

Let the original price of the transistor be x.

Therefore,

$x - .1x = 450$

$.9x = 450 \\ x = \frac{450}{.9} \\ x = \frac{4500}{9} \\ x = 500$

Therefore, the cost price of the transistor is (B) 500.
