For what value of 'K' will the pair of equations 3x+4y=12 and kx+12=30 does not have a unique solution ?

For what value of 'K' will the pair of equations 3x+4y=12 and kx+12=30 does not have a unique solution ? Correct Answer 9

3x + 4y = 12 এবং kx + 12y = 30 দুটি সমীকরণ। যদি, 3/k = 4/12 হয় তাহলে সমীকরণ জোটটির অসংখ্য সমাধান থাকবে। এখন, 3/k = 4/12 4k = 12 × 3 k = 36/4 k = 9

(A) Value of ‘r’ (B) Value of ‘s’ (C) Volume of the 60% spirit solution mixed initially (D) If 9 liters of r% spirit solution was mixed initially, what was the volume of the s% spirit solution thus obtained?
A chemical solution appears green when the salt concentration is 8 grams per litre (gpl) and red when it is 10 gpl. Pure water was added to the solution of 1 litre of 15 gpl solution till it turned green. Then 125 ml of the green solution is taken out and x grams of salt is added to the green solution to make it red. Another 500 ml of the final solution was taken out and y litres of green solution is added to get a resultant solution of concentration 9.6 gpl.  Assume adding salt doesn’t change its volume and find the ratio of x and y.
