A company blends two varieties of tea from two different tea gardens, one variety costing Rs.20 per kg and other Rs.25 per kg, in the ratio 5:4. He sells the blended tea at Rs.23 per kg. Find his profit percent?
3.5
Let the quantity of two varieties of tea be 5x and 4x respectively
Now,
SP =23×9x = 207x
CP = 20×5x + 25×4x =200x
Profit=7x200×100 =3.5%
