The letters are increasing by four increments. You can count this on your hand like this:

Thumb: a
Pointer Finger: b
Middle Finger c
Third finger: d
Pinky finger: e

This shows that each letter is on the thumb and pinky. Make sure you reset each count. So in this case 'e' becomes the thumb (so you sort of count it twice like this).

If you're really in a hurry on this it is a good guess that y,c is the correct response because this is the only answer that has a letter AFTER 'u'.

11) A father's age is five times his son's age. Four years ago the father was 9 times older than his son. How old are the father and son at present?

30yrs and 6yrs

25yrs and 5yrs

40yrs and 8yrs

None of these

You can solve this by rough estimation given you have multiple choice here. You can quickly see that each of the first 3 answers satisfy the condition that the father is currently 5 times the age of the son.

By subtracting 4 years from each age in each answer you will see them as follows:
a: 26 and 2
b: 21 and 1
c: 36 and 4

Now it is clear that the answer is c: 40 and 8 (because 4 x 9 = 36 and 5 x 8 = 40). These questions are why it is important to learn your multiplication tables prior to testing.

13) The sum of ages of 5 children born at the intervals of 3 years each is 50 years. What is the age of the youngest child?

4 years

8 years

10 years

None of these

Let the ages of children be x, (x + 3), (x + 6), (x + 9) and (x + 12) years.

Then, x + (x + 3) + (x + 6) + (x + 9) + (x + 12) = 50

5x = 20

x = 4.

Age of the youngest child = x = 4 years.

Explanation

Let the ages of children be x, (x + 3), (x + 6), (x + 9) and (x + 12) years.

Then, x + (x + 3) + (x + 6) + (x + 9) + (x + 12) = 50

5x = 20

x = 4.

Age of the youngest child = x = 4 years.
