# Problems On Ages Shortcuts

Problems on Ages is one of the questions asked in every Bank Exam. When you know that this is a sure question, why not prepare yourself well to stand up to the competition. Equip yourself with this Problems on Ages shortcuts and you can solve problems on ages like a PRO. And if you know divisibility tricks, its cake walk for you. You can use both tricks to solve the problem quickly with accuracy.

Let me walk you through few examples to get an understanding of the shortcut.

### Problems on Ages Examples

#### Example 1:

Present ages of S and A are in the ratio of 5:4 respectively. Three years hence, the ratio of their ages will become 11:9 respectively. What is A’s present age in years?

A)40 years

B)43 years

C)24 years

D)27 years

E)None of the above

**Step 1:**Write down the condition 1 given in question as follows

Present ages of S & A= 5:4

And we need to find A’s present age.

**Step 2:** Observe the options given in answer and find out which option is exactly divisible by 4.

We see that,

option A) 40/4=10 Exactly divisible by 4 so this could be the answer.

option B) 43/4 Not exactly divisible by 4

option C) 24/4=6 Exactly divisible by 4 so this could be the answer.

option D) 27/4 Not exactly divisible by 4.

So we have 2 options A and C exactly divisible by 4.

**Step 3:** Since we have 2 options satisfying condition 1. We need to check the options for condition 2 to see which among them is the answer.

** Step 4:** Condition 2 is Three years hence, the ratio is 11:9 is given.

First, we shall add 3 years to each of the options to get the age after 3 years(3 years hence)and divide each of the options by 9(A’s part)

We see

Option A) 40+3=43 years 43/9= Not exactly divisible by 9.

Option B) 43+3=46 years 46/9= Not exactly divisible by 9.

Option C) 24+3=27 years 27/9= Exactly divisible by 9.

Option B) 27+3=30 years 30/9= Not exactly divisible by 9.

We see that only option C satisfies condition 2.

Therefore, we can say that option C is the correct answer as it satisfies both condition 1 and condition 2.

A’s present age is 24 years.

#### Example 2:

Six years ago, the ratio of the ages of K and S was 6:5. Four years hence, the ratio of their ages will be 11:10. What is S’s age at present?

A)18 years

B)16 years

C)20 years

D)25 years

E)None of the above

**Step 1: **Condition1 given in the question is 6 years ago, the ratio was 6:5 is given

First, we shall subtract 6 years from each of the options to get the age before 6 years(6 years ago)and divide each of the options by 5(S’s part)

We see that,

Option A) 18-6=12 years 12/5 Not exactly divisible by 5.

Option B) 16-6=10 years 10/5=5 Exactly divisible by 5.

Option C) 20-6=14 years 14/5 Not exactly divisible by 5.

Option D) 25-6=19 years 19/5 Not exactly divisible by 5.

We see that only option B satisfies condition 1.

Thus, we can say that option C is the correct answer as it is the only option which satisfies the condition1.

We do not have 2 options satisfying condition1, so no need to check if the options satisfy condition 2. We can stop here and save a few seconds here.

S’s present age is 16 years.
