Question

In what proportion should one variety of oil at rs. 9.50 per kg be mixed with another at rs. 10 per kg to get a mixture worth rs. 9.60 per kg ?

Answer 1

9.5 10
——. ——

9.6

(10-9.6) (9.6-9.5)
= 0.4 0.1

4/10:1/10
= 4:1

Answer 2

The  proportion should. rs. 9.50 per kg of the  one variety of oil  mixed with  rs. 10 per kg of  the another variety of oil  to get rs.9.60 per kg of  the  mixture 4:1.

Step-by-step explanation:

Given:

rs. 9.50 per kg of the  one variety of oil  mixed with  rs. 10 per kg of  the another variety of oil  to get rs.9.60 per kg of  the  mixture.

To Find:

The  proportion should. rs. 9.50 per kg of the  one variety of oil  mixed with  rs. 10 per kg of  the another variety of oil  to get rs.9.60 per kg of  the  mixture.

Formula Used:

Quantity of One variety oil/ Quantity of Another variety oil = (Cost Price of Another variety oil – Mixture Price)/( Mixture  Price - Cost Price of One variety oil  )

Solution:

As given - rs. 9.50 per kg of the  one variety of oil  mixed with  rs. 10 per kg of  the another variety of oil  to get rs.9.60 per kg of  the  mixture.

Cost Price of 1 kg of  One variety oil = rs 9.5

Cost Price of 1 kg of  Another variety oil = rs 10

Cost Price of  1 kg of Mixture  Price = rs 9.6

Applying formula no.01.

Quantity of One variety oil/ Quantity of Another variety oil = (Cost Price of Another variety oil – Mixture Price)/( Mixture  Price - Cost Price of One variety oil  )

Quantity of One variety oil/ Quantity of Another variety oil =(10-9.6)/(9.6-9.5)

= (0.40/(0.1)

 = 4/1

Thus, the  proportion should. rs. 9.50 per kg of the  one variety of oil  mixed with  rs. 10 per kg of  the another variety of oil  to get rs.9.60 per kg of  the  mixture 4:1.
