Correct Answer is: Rs.8,000

Explanation:

Let C.P. of 1 fan = Rs.x

CP of 1 blower = Rs.y

CP of 1 table = Rs.1000 (given)

\(\therefore \Large 4x+3y = 16500\)

\(\Large 2x+2y+2 \times 1000 = 12000\)

=> 2x + 2y = 12000 - 2000 = 10000

=> x + y = 5000

Equation (ii) x 4 - (i),

y = 20000 - 16500 = 3500

=> x = 5000 - 3500 = 1500

\(\therefore 3x + y = \Large 3 \times 1500 + 3500\)

= Rs.8000
