Question

figures and number relationship
27,5,8
64,11,15
125,18,?
options are:
A) 11
B)15
C)13
D)17​

Answer 1

Answer:

first number is 27 ===> 3³

now here the magnitude of difference between the remaining two digits is 3 (8-5)

similarly 64====> 4³

now the magnitude of difference between remaining two numbers ==> 15 - 11 ===> 4

now 125 ===> 5³

the magnitude of difference between the remaining two numbers should be 5.

therefore the next digit can be 23 or 13 .

but as per options ....it's 13.

note: the magnitude of 3 is 3

the magnitude of -3 is also 3

ok??? that is what magnitude means ....here sign doesn't matter
