A. 2:5
B . 3:5
C. 5:3
D. 5:2​

Answer 1

Answer:

2:5

Step-by-step explanation:

CP of first tea = Rs. 192 per kg.

CP of Second tea = Rs. 150 per kg.

Mixture is to be sold in Rs. 194.40 per kg, which has included 20% profit. So,

SP of Mixture = Rs. 194.40 per kg.

Let the CP of Mixture be Rs. X per kg. Therefore,

X + 20% of X = SP

6X5

= 194.40

6X = 194.40 *5

X = Rs. 162 per kg.

Let N kg of first tea and M kg of second tea to be added.

Now, Using Alligation,

We get,
