*Question 01*

**A trader mixes three varieties of groundnuts costing ₹50, ₹20 & ₹30 per kg in the ratio of 2:4:3 in terms of weight and sells the mixture at ₹33 per kg. What percentage of profit does he make?**

**Given:**

The ratio of 3 varieties of ground nuts in terms of weight = 2:4:3

Let the weight of 3 varieties be 2x, 4x & 3x (in kg),

So the total weight is ==>2x + 4x + 3x = 9x kg

Also, the cost of 3 varieties are ₹50, ₹20, ₹30 per kg respectively.**Therefore CP **= (2x * 50 ) + (4x * 20) + (3x * 30) = 100x + 80x + 90x =** 270x**

Also given SP = ₹33/kg**Therefore total SP = ₹33 x 9x = 297x**

So,

**Profit %**= {(SP-CP)/CP} * 100

= { (297x-270x)/270x } * 100

= 27/270 * 100

=10%**Hence, the trader makes 10 profit**
