Problema Solution
vijay said to his wife, when I was 1/3rd of your age, you were 1/4th of my age. If their combined age is 62. What is the difference between their age?
Answer provided by our tutors
let
v = vijay's present age
w = wife's present age
the difference between their ages is: v - w
when vijath was: w/3 years old his wife was v/4 but the difference between their ages was the same, that is:
w/3 - v/4 = w - v
their combined age is 62:
v + w = 62
by solving the system of equations:
w/3 - v/4 = w - v
v + w = 62
we find:
v = 196/17
w = 62 - (196/17)
click here to see the step by step solution of the system of equations:
v - w = 196/17 - (62 - (196/17)) = 2*(196/17) - 62 = 662/17 = 38 16/17 = 39 years approximately
the difference between their age is 39 years approximately.
