In 80 ml of syrup, Ibuprofen and paracetamol are in the ratio of 2 : 3. This syrup is mixed with 120 ml of another syrup of ibuprofen and paracetamol. In the resultant syrup, paracetamol is 61.5%. Then find out the ratio of paracetamol and ibuprofen in 120 ml syrup. |
5 : 3 8 : 5 3 : 5 2 : 3 |
3 : 5 |
80 ml 120 ml Syrup A Syrup B ----------------- ----------------- ↓ ↓ ↓ ↓ ratio of I P I P ratio 2 : 3 ? : ? quantity 32 48 5R = 80 So, 2R = 32 ml & 3R = 48 ml Resultant syrup = Syrup C (80 ml + 120 ml = 200 ml) ratio of P I 61 .5 % 39.5 % ( given ) 200 × 61.5% = 123 ml 200 × 39.5% - 77ml Quantity of paracetamol in 120 ml of syrup is = 123 - 48 = 75 ml Quantity of Ibuprofen in 120 ml of syrup is = 77 - 32 = 45 ml 120 ml syrup B ratio I : P 45 : 75 3 : 5 Hence the required ratio in syrup B is 5 : 3 |
