hence answer is 82.
17 : 52 :: 1 : ?
3

in the same way,
hence correct answer is 4.
6 : 222 :: 7 : ?
210
336
343
350
in the same way
hence 350 is correct answer.
68 : 130 :: ? : 350

240
here,
Hence correct answer is 222.
49 : 81 :: 100 : ?
64
144
169
None of these
Here,
the relationship is
x² : (x+2)²
that is
7²=49 : (7+2)²=81
10²=100 : (10+2)²=144
hence correct answer is 144.
149 : 238 :: 159 : ?
248
261
268
here, the relation is
x = x+89
soo
149 : 149+89 =238
159 : 159 + 89 = 248
hence, correct answer is 248.
Choose the similar set to given set.
( 223, 324, 425 )
( 225, 326, 437 )
( 451, 552, 636 )
( 554, 655, 756 )
( 623, 723, 823 )
In each set, 2nd number = first number + 101
and 3rd number = 2nd number + 101
hence, correct answer is ( 554, 655, 756 )
Given set, ( 8, 3, 2 )
( 10, 6, 5 )
( 63, 8, 3 )
( 95, 24, 5 )
( 168, 15, 4 )
in each set,
first number= second number2-1
second number = third number2 -1
hence correct answer is ( 63, 8, 3 ).
