Question : Directions: Which one set of letters/numbers when sequentially placed at the gaps in the given letter series shall complete it?
xy_kx_zk_yzkxyz_ _
Option 1: zyxkx
Option 2: zykxz
Option 3: zkxyk
Option 4: zxykx
Correct Answer: zyxkx
Solution :
Given:
xy_kx_zk_yzkxyz_ _
To fill the series we have to divide the series – xy_k / x_zk / _yzk / xyz_ / _
Let's check each option –
First option:
zyxkx; xy
z
k / x
y
zk /
x
yzk / xyz
k
/
x
(xyzk is repeated in the series.)
Second option:
zykxz; xy
z
k
/
x
y
zk
/
k
yzk
/
xyz
x
/
z
(No repeated pattern has been found.)
Third option:
zkxyk; xy
z
k
/
x
k
zk
/
x
yzk
/
xyz
y
/
k
(No repeated pattern has been found.)
Fourth option:
zxykx; xy
z
k
/
x
x
zk
/
y
yzk
/
xyz
k
/
x
(No repeated pattern has been found.)
So, the series becomes→xyzkxyzkxyzkxyzkx. Hence, the first option is correct.
