Wipro Company Numerical Ability Alligation or Mixture

A producer of tea blends two varieties of tea from two tea gardens one costing Rs 18 per kg and another Rs 20 per kg in the ratio 5 : 3. If he sells the blended variety at Rs 21 per kg, then his gain percent is

a. 10
b. 12
c. 19
d. 22

Read Solution (Total 3)

its
(20-x)/(x-18)=5:3
from here x=75/4
now the sell price is 21
and the cost price is 75/4
so profit is 12%

Suppose he bought 5 kg and 3 kg of tea.
Cost Price = Rs. (5 x 18 + 3 x 20) = Rs. 150.
Selling price = Rs. (8 x 21) = Rs. 168.
Profit = 168 - 150 = 18

So, Profit % = (18/150) * 100 = 12%

let 5x , 3x
CP=5x*18+3x*20=150x
SP=(5x+3x)*21=168x
hence SP=CP(1+p/100)
168x=150x(1+p/100)
p=12%
