Question: 23
The second lowest number of five consecutive odd number series is four more than the 5/12th of the third Nghest number of a tive consecutive even number
series. If the average of five consecutive even number series is 60, then find the difference between the highest number of both the series?
Answers
difference between then is 29
Answer:
Difference between the highest number of both the series = 29
Step-by-step explanation:
Let us take,
The five consecutive odd numbers be 2n-3, 2n-1, 2n+1, 2n-3, 2n+5, for any natural number 'n'
and the five consecutive even numbers be 2m-4, 2m -2, 2m, 2m+2, 2m+4, for any natural number 'm'
The second-lowest number in this odd number series = 2n-1
The third-highest number in the even number series = 2m
Required to find,
Difference between the height number of both the series
Given,
The second-lowest number odd number series = 4 + X third-highest number in even number series.
That is,
2n - 1 = 4 + x 2m --------------(1)
Also given,
The average of the even numbers = 60
That is,
= 60
2m = 60
Hence the even number series = 2m-4, 2m -2, 2m, 2m+2, 2m+4
= 60-4, 60-2, 60, 60+2, 60+4
= 56,58,60,62,64
The even number series = 56,58,60,62,64
From equation (1) we get,
2n - 1 = 4 + x 60
2n -1 = 4 + 25 = 29
2n -1 = 29
2n = 30
Hence, the odd number series = 2n-3, 2n-1, 2n+1, 2n-3, 2n+5
= 30 -3, 30 - 1, 30 +1, 30+3, 30 +5
= 27, 29, 31, 33, 35
The odd number series = 27, 29, 31, 33, 35
Difference between the highest number of both the series = 64- 35 = 29
Hence,
Difference between the highest number of both the series = 29
