2 : 3 : 4. Find the cost of each item.

Answer 1

Answer:

let the cost be = x

2x+3x+4x=150

9x=150=150/9

x=50/3

first item is 100/3

second item is 50

third item cost 200/3

Answer 2

Answer:

100, 150, 200

Step-by-step explanation:

Let the cost be 2x,3x and 4x

Average = Sum of all observation/ number of observation

2x+3x+4x/3= 150

9x/3=150

3x=150

x=150/3

x=50

2x=2(50)=100

3x=3(50)=150

4x=4(50)=200

Hence, the cost is 100,150,200
