A has three daughters whose ages are in the ratio 7 ∶ 8 ∶ 9 (at present). Their husbands are 3, 2 and 6 years respectively elder to their wives. Each one of the couple has a child whose age is 1/5th the sum of ages of their parents. If sum of age of the grandchildren of A is 31, then what is the sum of ages of the son-in-laws of A? (in years) All the ages are measured at present. Correct Answer 83

Let the ages of the daughters be 7a, 8a and 9a respectively

∴ Ages of their husbands = 7a + 3, 8a + 2 and 9a + 6

Age of the kid of first couple = 1/5 × (7a + 7a + 3)

⇒ 1/5 × (14a + 3) = 2.8a + 0.6

Age of the kid of second couple = 1/5 × (8a + 8a + 2)

⇒ 3.2a + 0.4

Age of the kid of third couple = 1/5 × (9a + 9a + 6)

⇒ 3.6a + 1.2

Sum of ages of grandkids of A = 2.8a + 0.6 + 3.2a + 0.4 + 3.6a + 1.2

⇒ 9.6a + 2.2 = 31

⇒ 9.6a = 29.8

∴ a = 3

Ages of husbands = 21 + 3 = 24

⇒ 24 + 2 = 26

⇒ 27 + 6 = 33

∴ Sum of ages of son-in-laws = 24 + 26 + 33 = 83 years

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 ?
