Question

Find the blank space: \[5 \times \_\_\_ = 31 \times \_\_\_\].

Answer 1

Hint: As we know the product of two minutes can be taken by assuming either of two members in first place and other one in the second place. So, any one of the two numbers can behave as rumples or a multiplicand.

Complete step-by-step solution
\[5 \times \_\_\_ = 31 \times \_\_\_\] .
The two values on both sides will be equal only if they are the same in this case.
One value on the left hand side is 5 and one value on the right hand side is 31. So, the second value on the left hand side will be 31 & second value on right hand side will be 5 then they will be equal.

Therefore,
\[5 \times \underline {\,\,\,31\,\,\,} \] = \[31 \times \underline {\,\,\,5\,\,\,} \]

 So, the answer is \[31,5\].

NoteThe two words, “arithmetic logic,” strike terror into the hearts of people who have been out of school for a while or who have concentrated their studies in the humanities. The phrase “arithmetic logic” is probably equally as terrifying as it is puzzling. The quantitative reasoning test includes arithmetic problems as well as questions asking test takers to evaluate a set of facts. Each problem is presented as a short verbal description of a situation that includes some numerical facts.
Remember \[a \times b = b \times a\].
