Answer 2

Given :- if 32:961 and 40 : 1521, then what number shall replace X in 50:X ?

Solution :-

Logic :- n : (n - 1)²

Explanation :-

32 : 961 :-

→ 32 : (32 - 1)²

→ 32 : (31)²

→ 32 : 961

similarly,

40 : 1521 :-

→ 40 : (40 - 1)²

→ 40 : (39)²

→ 40 : 1521

therefore,

50 : X :-

→ 50 : (50 - 1)²

→ 50 : (49)²

→ 50 : 2401 .

Hence, 2401 will replace the X .
