Aptitude Problems on Ages Test Paper 2

The Correct answer is (A)

Explanation:

Let present age of son is X and present age of father is (44 -X).

As per question, after 6 years;

3(X+6) = (44 - X) +6

3X +18 = 50 - X

4X = 50 - 18

4X = 32

X = 8 years

∴Present age of son = 8 years

And, present of father = 44 - 8 = 36 years

Solution 2;

The Correct answer is (B)

Explanation:

Let Vijay is X years old now.

As per question, 10 years ago;

(X-10) = 18 ? 10

X -10 = 24

X = 24 +10 = 34 years

The Correct answer is (A)

Explanation:

Let the age of son is X and age of father 7X

Age of son after 10 years = X+10

Age of father after 10 years = 7X + 10

As per question, after 10 years;

3(X+10) = 7X + 10

3X + 30 = 7X + 10

4X = 20

X = 5 years

∴Age of father now = 7 * 5 = 35 years

The Correct answer is (B)

Explanation:

Let 12 years ago age of Badri was X years and age of Budh was 2X.

So, present age of Badri = X + 12

And, present age of Budh = 2X + 12

As per question;

6X + 36 = 4X + 48

2X = 12

X = 6

Present age of Badri = 6 + 12 = 18 years

Present age of Budh = 2*6 +12= 24 years

Required difference between their ages = 24 - 18 = 6 years

The Correct answer is (C)

Explanation:

Let two years ago, the ages of Naresh and Suresh was 3X and 2X.

So one year hence, the ages of Naresh and Suresh would be 3X+3 and 2X+3 respectively.

As per question;

15X + 15= 14X + 21

X = 6

Present age of Naresh =3*6 + 2 = 20 years

Present age of Suresh = 2*6 + 2 = 14 years

∴Sum of their present ages = 20 + 14 = 34 years
