] | B | Suppose the can initially contains 7x and 5x litres mixtures A and B
respectively
Quantity of A in mix. left =[7x –7/12 * 9 ] =[7x –21/4]
Quantity of B in mix. left =[5x –5/12 *9 ] = [ 5x - 15/4 ]
Therefore [ 7x-21/4 ] =7/9 or 28x-21 = 7/9
[5x-15/4]+9 20x+21

] | C | Severe mitral stenosis occurs with a valve area of less than 1 cm2 (The normal mitral valve orifice area is approximately 4-6 cm2). As the valve progressively narrows, the resting diastolic mitral valve gradient, and hence left atrial pressure, increases. This leads to transudation of fluid into the lung interstitium a... |
