The area of a rectangle gets reduced by 12 square units,if its length is reduced by 6 units and breadth is increased by 4 units.If we increase the length by 4 units and breadth by 2 units, then the area is increased by 63 square units. Find the length and breadth of the rectangle.

Correct

Explanation :
Length = x; Breadth = y
xy – (x-6)(y+4) = 12
4x – 6y = 12 —(i)
(x+4)(y+2) – xy = 63
4y + 2x – 55 = 0 —(ii)
solving (i) and (ii)
x = 13.5m ; y = 7m

Incorrect

Explanation :
Length = x; Breadth = y
xy – (x-6)(y+4) = 12
4x – 6y = 12 —(i)
(x+4)(y+2) – xy = 63
4y + 2x – 55 = 0 —(ii)
solving (i) and (ii)
x = 13.5m ; y = 7m

A container is filled with liquid, 8 part of which are water and 12 part milk. How much of the mixture must be drawn off and replaced with water so that the mixture may be half water and half milk?

Correct

Explanation :
Container initially contains – 20L of liquid
Quantity of milk in new mixture = (12 -12x/20)L
Quantity of water in new mixture = (8 – 8x/20 + x)L
(12 – 12x/20) = (8 – 8x/20 + x)
X = 10/3
Part of mixture replaced = 1/20 * 10/3 = 1/6

Incorrect

Explanation :
Container initially contains – 20L of liquid
Quantity of milk in new mixture = (12 -12x/20)L
Quantity of water in new mixture = (8 – 8x/20 + x)L
(12 – 12x/20) = (8 – 8x/20 + x)
X = 10/3
Part of mixture replaced = 1/20 * 10/3 = 1/6

Downstream speed = 48/20 = 2.4 kmph
Upstream speed = 48/24 = 2 kmph
speed of boat in still water =1/2 (2.4 + 2) = 2.2 kmph

Incorrect

Explanation :
Downstream speed = 48/20 = 2.4 kmph
Upstream speed = 48/24 = 2 kmph
speed of boat in still water =1/2 (2.4 + 2) = 2.2 kmph
