The ratio of spirit and water in two mixturers of 20 litre and 36 litre is 3 : 7 and 7 : 5 respectively. Both the mixtures are mixed together. Now the ratio of the spirit and water in the new mixture is
-
- 25 : 29
- 9 : 10
- 27 : 29
- 27 : 31
Correct Option: C
In 20 litres of mixture,
| Spirit = | × 20 = 6 litres, | |
| 10 |
Water = 14 litres
In 36 litres of mixture
| Spirit = | × 36 = 21 litres | |
| 12 |
Water = 15 litres
∴ Required ratio = (21 + 6) : (14 + 15)
= 27 : 29
