One cup has juice and water in the ratio 5 : 2, while another cup of the same capacity has them in the ratio 7 : 4, respectively. If contents of both the cups (when full) are poured in a vessel, then what will be the final ratio of water to juice in the vessel?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 25 : 52
| Juice | water | total | |
| CUP1 | 5 | 2 | 7 units |
| CUP2 | 7 | 4 | 11 units |
the capacity of both the cup is the same.
To make it equal multiply the content of the first cup by 11 and the second cup by 7.
| Juice | water | total | |
| CUP1 | 55 | 22 | 77 units |
| CUP2 | 49 | 28 | 77 units |
Content of juice and water in Cup3 will be in the ratio of (55 + 49) : ( 22 + 28) = 104 : 50 = 52 : 25
Ratio of water to juice = 25 : 52.
