The combined fat for all the 3 different kinds of milk, gives the following equation.
x + 2y + 3z = 1.5 (x + y + z)
Solve this equation.
2y - 1.5y + 3z - 1.5z = 0.5x
5y + 15z = 5x
y + 3z = x (Which is Option A)
x + 2y + 3z = 1.5 (x + y + z)
Solve this equation.
2y - 1.5y + 3z - 1.5z = 0.5x
5y + 15z = 5x
y + 3z = x (Which is Option A)
ohhh!!! this was so easy but just cudnt comprehend it ... thnks guysksh wrote:Hi Akash,
we need to represent three solutions in terms of their percentage as follows:
1(x)+2(y)+3(z)=1.5(x+y+z)
0.5x=0.5y+1.5z
multiply botth sides by 2
x=y+3z which is choice A
Hope you get it
