Answer:
Highest received is by department Y
Step-by-step explanation:
Given that the research funds of a certain company were divided among three departments, X, Y, and Z.
The research funds received by departments X and Y were in the ratio 3 to 5, respectively.
The research funds received by departments X and Z were in the ratio 2 to 1, respectively
X:Y = 3:5
X:Z = 2:1
X is common in both the equations so let us take lcd for 3 and 2 = 6
Multiply I equation by 2 and II equation by 3
X:Y = 6:10
X: Z = 6:3
Since X has the same numerical value we can combine these two tog et
X:Y: Z =6:10:3
Highest received is by department Y
