Question

Find the missing number in the sequence $ 865:532::976:? $

Answer 1

Hint: We have to solve the problem using the concept of general intelligence. The process is to increase the digits of the previous digit to get the next digit. We follow the same rule for both numbers.

Complete step-by-step answer:
The given problem cannot be solved in normal methods of mathematics. The given signs of $ :: $ aren’t of proportionality.
We can’t express $ 865:532::976:? $ as $ \dfrac{865}{532}=\dfrac{976}{?} $ .
This question is an example of a general intelligence question. We have to understand the rule following which we have converted 865 to 976. We have to follow the same process to find the missing number created from 532.
Both 865 and 976 have three digits. Every digit in 865 has been increased by 1.
So, the relation is to increase the digits.
We follow the same process for 532.
We increase every digit of 532 to get the missing number.
We get 643.
The sequence is $ 865:532::976:643 $ .
So, the correct answer is “ $ 865:532::976:643 $ ”.

Note: A proportion is an equation that says that two or more ratios are equal. For instance if one package of cookies contains 20 cookies that would mean that 2 packages contain 40 cookies.
