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)∴4x+3y=16500
2x+2y+2×1000=12000
=> 2x + 2y = 12000 - 2000 = 10000
=> x + y = 5000
Equation (ii) x 4 - (i),
y = 20000 - 16500 = 3500
=> x = 5000 - 3500 = 1500∴3x+y=3×1500+3500
= Rs.8000
