Question

A producer blends two varieties of tea from two different tea gardens. One costing is Rs. 15/kg and another costing Rs. 20 /kg in the ratio of 7: 3. He sells the blended variety at Rs. 18.15/ kg. Determine his profit/ loss %.

• A. 10%
• B. 15%
• C. 18%
• D. 24%

Answer 1

The correct option is A

10%

C.P of 7 kg of $1^{st}$ kind of tea = Rs. 15 $\times$ 7 = Rs. 105

C.P of 3 kg of $2^{nd}$​ kind of tea = Rs. 20 $\times$ 3 = Rs. 60

C.P of 10 kg of tea = Rs. (105 + 60) = Rs. 165

S.P of 1 kg (mixed tea) = Rs. 18.15

S.P of 10 kg (mixed tea) = Rs. 18.15 $\times$ 10 = Rs. 181.50

Gain on Rs. 165 = Rs. (181.50 – 165.00) = Rs. 16.50

Gain$\%$ = $\frac{16.5\times 100}{165}$ = 10$\%$
