How to Solve
Let, the age of Sonu and Monu 7 years ago be 6X and 5X respectively.
So, ( 6X + 7 ) + 3 / ( 5X + 7 ) + 3 = 11 / 10
10 ( 6X + 10) = 11 ( 5X + 10 )
5X = 10
X = 2

So, Monu’s present age is ( 5x + 7 ) = 17 years.

Answer: Option (C)
How to Solve
Let, Sanjay’s present age is X years.
So, Rahul’s present age is ( X + 6 ) years.
( X + 6 ) + 12 = 3 ( X – 12 )
12X + 72 = 3X – 36
12X – 3X = – 36 – 72
9X = 108
X = 12.

The present age of Sanjay is 12 years.

Answer: Option (A)
How to Solve
Step 1: Let 10 years before Golu, Sonu, and Bulu’s ages are 3X, 4X and 5X respectively.
Then,
( 2X + 10 ) + ( 4X + 10 ) + ( 5X + 10 ) = 96
11X = 66
X = 6

Example #14

Ratio of ages of M and N before 4 years was 3 : 5. If the sum of present ages of M and N is 64 years. What is the present ages of M and N?

  1. 27 Years
  2. 39 Years
  3. 48 Years
  4. 60 Years

Show Answer Show How to Solve Open Rough Workspace

Answer: Option (B)
How to Solve
Step 1: M : N = 3 : 5 and M + N = 64 years.
Sum of both ages 4 years ago is ( 64 – 8 ) = 56

Step 2: M = ( 56 / 8 ) x 3 = 7 x 3 = 21 years
and N = (56 / 8 ) x 5 = 5 x 7 = 35 years.

Step 3: present age of M = ( 21 + 4 ) = 25 years
and present age of N = ( 35 + 4 ) = 39 years.

      that means,whenever before/ago is there, actually we have to do ‘-‘ but in those particualr problems we are calculating for the present age,thats why whenever before/ago is used “converting into present age i.e ‘+’ is using”.
      for eg:In question if they give 5 years before/ago P’s age is twice of Q.
      In problem solvation they are converting into present age i.e P+5=2(Q+5)
