Question:
I met a men who said if you can guess my age, i will pay you one dollar for each year that i have lived. I will also give you two hints. If you take my age and divide it by any odd number greater than 1 and less than 9 you will get a remainder of 1. But if you take my age and divide it by any even number greater than 1 and less than 9 you will not get a remainder of 1. how much money could you earn?
Answer:
The man's age is 106 years
Amount earned is $ 106.00
Step-by-step explanation:
Here we have
3 × a = Age +1
5 × b = Age +1
7 × c = Age +1
Age is even, therefore, a, b and c are odd numbers
Since 3, 5 and 7 are factors of Age + 1
Then, 3 × 5 × 7 is a factor. That is 3 × 5 × 7 = 105
Therefore, 105 + 1 or 106 is a possible solution as an even number divided by another even number will not have a remainder of 1.
The age of the man is 106 years
Therefore, the amount earned = $ 1.00/year × 160 years = $ 106.00
5(9-4)2-3^2 -3^2=9
5(9-4)2+9 9-4=5
5(5)2+9 5(5)=25
(25)2+9 (25)2=50
9+50=59
Answer:
2 52/67 (2.77611940...)
Step-by-step explanation:
See how many times 67 goes into 186:
2
Then the remainder is 52/67.
