Reasoning Questions for SSC CGL: 16th Jan 2020


Q1.If SMART is coded as 93180 and STUDY is coded as 902410, then how will EXAMPUR be coded as?
A.5813256          
B.4513628                                           
C.5813628           
D.5854628

Solution of Q1-
As,
SMART= S(19)M(13)A(1)R(18)T(20)
= S(1*9)M(1*3)A(1)R(1*8)T(2*0)
= S(9)M(3)A(1)R(8)T(0)
=93180
And
STUDY= S(19)T(20)U(21)D(4)Y(25)
= S(1*9)T(2*0)U(2*1)D(4)Y(2*5)
= S(9)T(0)U(2)D(4)Y(10)
=902410
Similarly,
EXAMPUR= E(5)X(24)A(1)M(13)P(16)U(21)R(18)
= E(5)X(2*4)A(1)M(1*3)P(1*6)U(2*1)R(1*8)
= E(5)X(8)A(1)M(3)P(6)U(2)R(8)
= 5813628
Thus, the correct answer is option C.
Q2.Which number will replace the question mark (?) in the following series?
71, 79, 95, 127, ?, 319
A.159    
B.165
C.191    
D.218
Solution of Q2-
Logic is-
71+8=79
79+16=95
95+32=127
127+64=191
191+128=319
Thus, the correct answer is option C.
Q3.In a code language. DENSITY is written as QGEWFZN. How will TRAITOR be written as in that language?
A.DTUMYUY      
B.DTULTUY
C.DCGMYUY      
D.KOUMYUY
Solution of Q3-
Thus, the correct answer is option A.
Q4.If TALK = 7 and TASTE = 44, then PRODUCT = ________.
A.84
B.34
C.43
D.49
Solution of Q4-
Logic- square of (number of letters)-6
As, TALK=square of 4-6=16-6=10
And TASTE= square of 5-6=25-6=19
Similarly,
PRODUCT= square of 7-6=49-6=43
Thus, Option C is the correct response.
