Answer: Option (A)
How to Solve
Let, their age ratio was 3 : 5 before Y years.
So,
50 – Y / 70 – Y = 3 / 5
5 ( 50 – Y ) = 3 ( 70 – Y )
250 – 5Y = 210 – 3Y
2Y = 40
Y = 20 years.

Example #3 – Problems Based on years ago Ages

The present ratio of ages of P and Q is 4 : 6. If the sum of present ages of P and Q is 50 years. Find the ages of P and Q before 4 years.

  1. P = 12 Years and Q = 22 Years
  2. P = 14 Years and Q = 24 Years
  3. P = 16 Years and Q = 26 Years
  4. P = 18 Years and Q = 28 Years

Answer: Option (C)
How to Solve
Let, ages of P and Q is X.
So, P and Q ages are 4X and 6C Gradually.
Now according to question Sum of present ages,
4X + 6X = 50
10X = 50
X = 5 years.

And then the present age of P is 4X = 4 x 5 = 20 years.
So, 4 years ago the age of P was ( 20 – 4 ) = 16 years.

Present age of Q is 6X = 6 x 5 = 30 years.
So, 4 years ago the age of Q was ( 30 – 4 ) = 26 years.

  1. P = 10 Years and Q = 20 Years
  2. P = 8 Years and Q = 20 Years
  3. P = 8 Years and Q = 18 Years
  4. P = 6 Years and Q = 14 Years

Show Answer Show How to Solve Open Rough Workspace

Answer: Option (B)
How to Solve
Let, the ages of P and Q are 3X and 5X respectively after 5 years.
Then,
( 3X – 5 ) + ( 5X – 5 ) = 38
8X – 10 = 38
8X = 48
X = 6

The ages of P after 5 years
= 6 x 3
= 18 years.

Then the ages of Q after 5 years
= 6 x 5
= 30 years.

The ages of P and Q before 5 years is
P = ( 18 – 10 ) = 8 years
Q = ( 30 – 10 ) = 20 years.
