Answer 1

Answer:

₹ 3,000

Step-by-step explanation:

Let cost price be x

Therefore,

3500 - x = (1/6) x

=> 7x = 21000

=> x = 3000

Answer 2

Answer:

Step-by-step explanation:

SP of the room heater= rs3500

gain= 1/6*CP

let CP be a

1/6*a=1/6a

SP-GAIN= CP

3500-1/6a= a

a+1/6a= 3500

6/6a+1/6a= 3500

7/6a= 3500

a= 3500*6/7= 3000

hence CP = rs3000
