Three containers A,B and C are having mixtures of milk and water in the ratio of 1:5 and 3:5 and 5:7 respectively. If the capacities of the containers are in the ratio of all the three containers are in the ratio 5:4:5, find the ratio of milk to water, if the mixtures of all the three containers are mixed together.  Pick one:  A) 53:115  B) 55:115  C) 115:55  D) 5:115  E) 115:53
Assume that there are 500,400 and 500 liters respectively in the 3 containers.   Then ,we have, 83.33, 150 and 208.33 liters of milk in each of the three containers.   Thus, the total milk is 441.66 liters.   Hence, the amount of water in the mixture is 1400-441.66=958.33liters.   Hence,   the ratio of milk to water is 441.66:958.33 =&gt; 53:115(using division by .3333)   The calculation thought process should be   (441*2+2):(958*3+1)=1325:2875   Dividing by 25 =&gt; 53:115.   53:115NSWER 53:115 53:115
