Solution

The correct option is A Rs. 355.68
Assume the cost components to be valued at 3x,4x,5x and 6x respectively.
New cost of components = 3.3x, 3.28x, 3.5x and 8.58x respectively
The original total cost was18x, the new one is 18.72x
The percentage change is 0.7218=4%
New cost of the article = Rs. 342×1.04 =Rs.355.68
