Q1. X’s age 3 years ago was three time the present age of Y. At present, Z’s age is twice the age of Y. Also, Z is 12 years younger than X. What is the present age of Z?
15 years
24 years
12 years
6 years
18 years
Solution:
Let present ages of all the three are X, Y and Z respectively.
X = 3Y + 3 …(i)
Z = 2Y …(ii)
X = Z + 12 …(iii)
From equations (i), (ii) and (iii)
X – 3Y = 3 and X – 2Y = 12
After solving these two resultant equations, we get
Y = 9 years
∴ Z’s present age = 18 years.
X = 3Y + 3 …(i)
Z = 2Y …(ii)
X = Z + 12 …(iii)
From equations (i), (ii) and (iii)
X – 3Y = 3 and X – 2Y = 12
After solving these two resultant equations, we get
Y = 9 years
∴ Z’s present age = 18 years.
