Question 48

In a certain code language, ‘231’ is written as ‘4-9-1’. What will be the code for ‘569' in that code language?

Solution

Given,

231 is coded as 4-9-1.

The pattern followed here is :

all numbers in the second number is the square of the digits of first number.

$$2^2=4,\ 3^2=9,\ 1^2=1$$

Similarly,

569 will be coded as 25-36-81

i.e; $$5^2=25,\ 6^2=36,\ 9^2=81$$

Hence, Option B is correct.
