​

Answer 1

Answer:

RS 800 is the price shopkeeper returned

Answer 2

Answer:

c) 1200

Step-by-step explanation:

Let cost price of transistor = Rs.x

According to the question,

CP of transistor = x×105100

and SP of transistor = (115x100+6)

Profit percentage = SP−CPCP×100

10=115x100+6−105x100105x100×100

10=(10x+600)100105x

105x = 100x + 6000

5x = 6000

x = Rs.1200
