The ratio of the amount of milk in container A to the amount of milk in container B is 52: 49, respectively. Find the ratio of the amount of mixture in container A to the amount of mixture in container B.

 Statement l: The ratio of the amount of water to the amount of milk in container A is 7:16, respectively.

6.A, B, C and D are four friends. Present average age of A, B, C and D is 29 years. Find the present age of C.

Statement l: Ratio of the present ages of A and C is 4:9. Ratio of the present ages of B and D is 5:3. The difference in the ages of A and B is 8 years.

Statement Il: Ratio of the age of C four years ago to the present age of D is 4:3. A is eight years younger to D. Age of B 8 years hence will be thrice the present age of A.
