Question

in what ratio should mix the 150 per kg and 200 per kg tea
to bring the priceof mixture 165 per kg​

Answer 1

Step-by-step explanation:

To:find:

In what proportion should tea of rs 150 per kg and rs 200 per kg be mixed so that the price of the mixture becomes rs 165 per kg.

Now:

Let the total tea added 150rs per kg =x

Let the total tea mixed 200rs per kg =y

Total mixture=x+y

Therefore

150x + 200y = 165(x + y)

⟹150x+200y=165(x+y)

⟹150x+200y=165x+165y

⟹150x−165x=165y−200y

⟹15x=35y

⟹ x/y=35/15

⟹x/y=7/3

⟹x:y=7:3
