Question

reasoning series question 40,60,47,53,54,?​

Answer 1

$\bigstar$ Question:

• What number will come in this question mark?

40 , 60 , 47 , 53 , 54 , ?

$\bigstar$ Solution:

• This is a series which is also called 'double series'.
• It is called so because it follows 'two series at a time'.

$\star$ 1st Series:

• The numbers who are following this series are:

40 , 47 , 54

• In this 1st series, +7 I'd added in each term.
• So 40 + 7 = 47, 47 + 7 = 54.

$\star$ 2nd series:

• The numbers which are following this series are:

60 , 53 , ?

• Here, we will observe that 7 is subtracted from each term.
• Therefore, 60 - 7 = 53, 53 - 7 = 46
• So the answer is 46.

$\bigstar$Answer:

$\therefore$ the number in place of 'question mark' is 46.

Answer 2

Question :-

40 , 60 , 47 , 53 , 54 , ?

• What will come in place of question mark

Answer :-

• 46 will come in place of Question mark

40 , 60 , 47 , 53 , 54 , 46

Solution :-

The given series is Double Series because it follows Two series at a time .

So, the first series is →

40 , 47 , 54

• In this series +7 is added in each term

40 + 7 = 47

47 + 7 = 54

The second Series :-

60 , 53 , ?

• In this series 7 is subtracted from each term

60 - 7 = 53

So,

53 - 7 = 46

So the number in place of question mark is 46
