Logical Reasoning Questions for RRB NTPC

if in some coding do is 35 then done is

solution:

take reverse letter code.

as, do=d(23)o(12)=23+12=35

similarly, done=d(23)o(12)n(13)e(22)=23+12+13+22=70

if road is coded as 38 then light can be coded as

solution:

take forward letter code.

as, road=r(18)o(15)a(1)d(4)=18+15+1+4=38

similarly, light= l(12)i(9)g(7)h(8)t(20)=12+9+7+8+20=56

if hotel is coded as 60 then how is plant coded as

solution:

take forward letter code.

as, hotel = h(8)o(15)t(20)e(5)l(12)=8+15+20+5+12=60

similarly, plant= p(16)l(12)a(1)n(14)t(20)=16+12+1+14+20=63

if late is coded as 38 then what is the code for make

solution:

take forward letter code.

as, late=l(12)a(1)t(20)e(5)=12+1+20+5=38

similarly, make=m(13)a(1)k(11)e(5)=13+1+11+5=30

if hello is coded as 35 and honest is coded as 48 then historic is coded as

solution:

Logic: (number of letters in the word given)*( number of letters in the word given + 2)

as, hello=(number of letters in hello)*( number of letters in hello + 2)

=(5)*(5+2)=5*7=35

and, honest=(number of letters in honest)*( number of letters in honest + 2)

=(6)*(6+2)=6*8=48

similarly, historic=(number of letters in historic)*( number of letters in historic + 2)

=(8)*(8+2)=8*10=180
