Two blends of a commodity costing Rs. 35 and Rs. 40 per kg. respectively are mixed in the ratio 2 : 3 by weight. If one–fifth of the mixture is sold at Rs. 46 per kg and the remaining at the rate of Rs. 55 per kg. the profit percent is
-
- 50
- 30
- 40
- 20
Correct Option: C
Let 5 kg of mixture be prepared.
∴ C.P. of 5 kg of mixture
= Rs. (2 × 35 + 3 × 40)
= Rs. (70 + 120)
= Rs. 190
Total S.P. of this mixture
= Rs. (46 + 4 × 55)
= Rs. (46 + 220) = Rs. 266
| ∴ Profit per cent = |  |  | × 100 | |
| 190 |
| = | = 40% = 1 | |
| 190 |
