Some Quizzes

[marydejong]

Hey, guys! I'd like to ask you to help me solve two quizzes I stuck on. I guess I think of all possible solutions and even consider asking to write my paper on Math to solve these:

1. Which number is hidden behind the question mark?

2. What time does the last watch show?

Hi,

1) 7

2) 7:10

[MartinHanak]

x = a + b

? = 7

last time = 7:10

[-MFra-]

[MartinHanak]

x=7.17 hr is not accurate value, it is rounded. Also you cannot display 7.17 value on watch 🙂

Accurate value is 7 1/6 hr, this means 7 hr 10 min. Therefore watch display shows ... 7:10

[-MFra-]

OK!

And the sum of digit values on the clock (appears to be) must be 8.
