the cost of making an article is divided among the material labour and wastage in the ratio 3 upon 2 : 2 :1 upon 2 if material costs rs 11.25, find the cost of the article​

Answer 1

Answer:

₹30

Step-by-step explanation:

ratio =>

=> material : labour : wastage

=> 3/2 : 2 : 1/2

=> 2 × 3/2 : 2 × 2 : 2 × 1/2

=> 3 : 4 : 1

so ratio of

material : labour : wastage

=> 3 : 4 : 1

now

given that cost of material = ₹11.25

let total cost of article be ₹x

so

X × 3/(3+4+1) = 11.25

=> X × 3/8 = 11.25

=> 3x = 11.25 × 8

=> x = 90/3

=> x = 30

now

cost of article = ₹30
