There are three containers of equal capacity. The ratio of Sulphuric acid to water in the first container is 3 : 2, that in the second container is 7 : 3 and in the third container it is 11 : 4. If all the liquids are mixed together, then the ratio of Sulphuric acid to water in the mixture will be :
-
- 61 : 29
- 61 : 28
- 60 : 29
- 59 : 29
Correct Option: A
In the new vessel, we have.
| Sulphuric acid = | + | + | |||
| 5 | 10 | 15 |
| = | = | ||
| 30 | 30 |
| Water = | + | + | |||
| 5 | 10 | 15 |
| = | = | ||
| 30 | 30 |
∴ Sulphuric acid : Water
| = | : | ||
| 30 | 30 |
= 61 : 29
