Test IQ together

The following is an IQ test, according to whether two people are synchronous to test the level of IQ.

On the road, a couple walked by side by side.

At first glance, they all started at the same time with their right feet. Then, because of the big stride of men, the three steps of women can keep up with the two steps of men.

How many steps should a woman take from starting with both right feet to stepping out with both left feet?

Is this the least common multiple?

A lot of people will think of this. The least common multiple of 3 and 2 is 6. Is it the same left foot in 6 steps?

No, it needs to be considered from the reality, as shown in the table below:

Male: right, left, right, left, right, left, right

Female: right, left and right, left, right, left, right, left and right, left and right

In this way, it is more obvious that it is impossible for men and women to step out with their left feet at the same time.

We should train ourselves from the abstract to the reality, from the reality to the abstract thinking leap transformation.
