Select the set in which the numbers are related in the same way as are the numbers of the following set.
(24, 15, 120)
(21, 19, 133)
(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13 – Operations on 13 such as adding/deleting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
SSC CGL Exam Paper 25 September 2024 : General Intelligence and Reasoning
Option:
a) (31, 9, 96)
b) (18, 16, 99)
c) (27, 12, 108)
d) (33, 10,170)
Solution:
Logic: Multiply fist two number and divide by 3 to get third number
(24, 15, 120) => 24 x15 = 360, 360/3=120
(21, 19, 133) => 21×19=300, 399/3=133
Now apply same logic to all options:
a) (31, 9, 96) => 31×9=279, 279/3=93 ( Not follow the logic)
b) (18, 16, 99) => 18×16=288, 288/3=96 ( Not follow the logic)
c) (27, 12, 108) => 27×12=324, 324/3=108 ( Follow the logic)
d) (33, 10,170) -> 33×10=330, 330/3=110 ( Not follow the logic)
Correct Answer : c) (27, 12, 108)
