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.
-
6 3.0 4.5 2.25 4.0 12 40 (a) (b) (c) (d) (e) Which of the following numbers will come in place of (c) ?
-
- 20.5
- 21.5
- 33.75
- 69.5
- 15
Correct Option: E
The given series is in the below pattern ,
First series :-
First term = 6
Second term = First term ÷ 2
⇒ Second term = 6 ÷ 2 = 3
Third term = Second term × 1.5
⇒ Third term = 3 × 1.5 = 4.5
similarly , we can calculate the all next terms .
........... and so on.
Second series :-
First term = 40
Second term = First term ÷ 2
⇒ Second term = 40 ÷ 2 = 20
Third term = Second term × 1.5
⇒ Third term = 20 × 1.5 = 30
Fourth term = Third term ÷ 2
⇒ Fourth term = 30 ÷ 2 = 15
Hence , the place value of (c) is 15 .
