Direction: In each of the following questions a number series is given. A number is given after the series and then (a), (b), (c), (d) and (e) are given. According to the given series, you have to form a new series which begins with the given number, and then answer the question asked.
-
1260 628 312 154 788 (a) (b) (c) (d) (e) Which of the following numbers will come in place of (d) ?
-
- 194
- 45.5
- 48
- 72.5
- None of these.
Correct Option: B
As per the details of question is given series in the form of ,
First series :-
First term = 1260
Second term = First term ÷ 2 - 2
⇒ Second term = 1260 ÷ 2 - 2 = 628
Third term = Second term ÷ 2 - 2
⇒ Third term = 628 ÷ 2 - 2 = 312
similarly , we can find the all others terms .
......... and so on .
Second series :-
First term = 788
Second term = First term ÷ 2 - 2
⇒ Second term = 788 ÷ 2 - 2 = 392
Third term = Second term ÷ 2 - 2
⇒ Third term = 392 ÷ 2 - 2 = 194
Fourth term = Third term ÷ 2 - 2
⇒ Fourth term = 194 ÷ 2 - 2 = 95
Fifth term = Fourth term ÷ 2 - 2
⇒ Fifth term = 95 ÷ 2 - 2 = 45.5
Hence , the place value of ( d ) is 45.5 .
