Will you take this Shanghai civil servant interview question? It is said that many high-achieving students have been defeated! Grandpa and Grandma are 90 years old, Grandpa is 70 years old, how old is Grandma? Are you as direct as I am

Will you take this Shanghai civil servant interview question? It is said that many high-achieving students have been defeated!

Grandpa and Grandma are 90 years old, Grandpa is 70 years old, how old is Grandma?

Are you also like me directly answering 20 years old? Unfortunately, you also became one of the elimination troops. So what's the answer?

Let's try to analyze it, this is a serious civil service examination question, starting from the basic requirements of the civil servant position to think, it should not be just a simple test of primary school students will do less than 100 addition and subtraction.

So, what does the interviewer want to examine? How can you find different entry points from a subject of less than 20 words?

Some netizens provided an idea: reasonable assumptions, bold verification, and finding other possibilities.

Think of this problem as an equation for applying the problem, where you can make a hypothesis about uncertainties under known conditions and get an answer; then, another hypothesis, to come up with another possibility.

I think that what the examiner wants may not be a cookie-cutter answer, but a logical ability of multiple thinking, that is, the ability to "break through the wall in the mind".

It turns out that its answer will never be a simple number. However, this is obviously beyond my ability, and I can't understand why the civil service exam has to come up with such a question.

Smart you, is there a reasonable answer? What different assumptions can you think of? What are your thoughts on this civil service exam question? (Welcome to share your wisdom)
