A question and three statements labeled (I), (II) and (III) are given. You have to decide which statement(s) is/are sufficient to answer the question. What is Surya's age? I. Surya and his sister are the only children in Ramesh's home. II. Surya's sister is elder to him by 5 years. III. Surya's sister just turned 15 this year. Correct Answer II and III are sufficient.

Statement 1-: Surya and his sister are the only children in Ramesh's home.

It means there are only two children in Ramesh's home. Nothing mentioned about their ages.

Statement 2-: Surya's sister is elder to him by 5 years.

It means if we have Surya's age then we can find his sister's age or if we have sister's age then we can find Surya's age.

Statement 3-: Surya's sister just turned 15 this year.

Here Surya's sister age is given.

By combining Statement 2, 3 we can say that Surya's age is 5 years less than his sister, and sister's age given is 15. So Surya's age is 10.

Hence, Statement 2,3 are sufficient.

Two boys are playing on a ground. Both the boys are less than 10 years old. Age of the younger boy is equal to the cube root of the product of the age of the two boys. If we place the digit representing the age of the younger boy to the left of the digit representing the age of the elder boy, we get the age of the father of the younger boy. Similarly, we place the digit representing the age of the elder boy to the left of the digit representing the age of the younger boy and divide the figure by 2, we get the age of the mother of the younger boy. The mother of the younger boy is younger than his father by 3 years. Then, what are the ages of elder and younger boys ?
