The Correct Option is A
Solution and Explanation
Cost price of comp system = Rs. A
Cost Price of color printer = Rs. B
0.9 A + 1.2 B= A + B
0.2 B = 0.1 A
A = 2B
(A+ B) - (1.05A + 0.85B) = 800
(2B + B) - (2.10B + 0.85 B) = 800
3B - 2.95 B = 800
0.05 B = 800
B \(=\frac{800}{5}\times100\)
= 16, 000.
So the correct option is (A)
