How many 9’s are there in the series which are preceded by 7 but not followed by 8?
4 2 9 6 7 9 2 4 7 9 8 4 7 9 3 6 8 9
What is the product of sum of even digits and sum of odd digits in the number
8 6 7 4 3 5 2?
Sum of even digits = 8 + 6 + 4 + 2 = 20
Sum of odd digits = 7 + 3 + 5 = 15
Product = 20 × 15 = 300
How many 8’s are there in the series which are preceded by 5 but not followed by 7?
4 3 8 6 5 8 2 3 5 8 4 7 5 8 7 4
What is the difference between the sum of even digits and sum of odd digits in the number
7 4 6 2 5 8 9 3?
Sum of even digits = 4 + 6 + 2 + 8 =20
Sum of odd digits = 7 + 5 + 9 + 3 = 24
Difference = 24 – 20 = 4.
