Two containers of equal capacity are full of a mixture of oil and water . In the first, the ratio of oil to water is 4:7 and in the second it is 7:11. Now both the mixtures are mixed in a bigger container. What is the resulting ratio of oil to water.	Choose the correct answer:	A) 149 : 247	B) 247 : 149	C) 143 : 241	D) 241 : 143	E) 341 : 243
Two Container C1, C2 of equal capacity x.   For C1:   Oil= 4/11 x   Water= 7/11 x   For C2   Oil= 7/18 x   Water = 7/11 x   Mix C1 and C2.   Total Oil= 4/11 x + 7/18 x = 149/198 x   Total Water= 7/11 x + 7/11 x = 247/198 x   resulting ratio of oil to water = (149/198 x) / (247/198 x)   = 149:247.   149 : 247NSWER:149 : 247
