Question

The ratio in which tea costing rate 192 per kg is to be mixed with tea costing race 150 per kg so that the next event sold for rs 190 4.40 per kg gives a profit of 20%

Answer 1

Answer:

Step-by-step explanation:

Option(B) is correct

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,

Thus,

N/M=162−150/192−162

N/M=12/30

N/M=2/5

⇒N : M = 2 : 5

Hope it helps you...

Answer 2

Answer:

if sp is Rs. 190.4 and profit 20%

then cp=190.4x100/120 = Rs.159

Alligation method:

192. 150

159

9. . 33

9:33 = 3:11 is the ratio of mixing
