In a certain code BREAKER is written as DPGBMCT. How is MOTHERS written in that code language?

A)
OMVIGPU

B)
UPGIVLO

C)
SRETHOM

D)
OMVIUPG


Correct Answer :

OMVIGPU


Explanation :

The given pattern is as follows:
B -> C -> D
R <- Q <- P
E -> F -> G
A -> B
K -> L -> M
E <- D <- C
R -> S -> T

That is why mothers is written as
M -> N -> O
O <- N <- M
T -> U -> V
H -> I
E -> F -> G
R <- Q <- P
S -> T -> U

Therefore, the code will be OMVIGPU.

In certain code language ‘nu ku pu’ mean ‘who are you’, ‘ku lu tu du’ means ‘you may come here’.What does ‘nu’ means in that code language?

150


D)

220



Correct Answer :

164


Explanation :

A = 1, B = 3, C = 5, D = 7, E = 9 .........N = 27, O = 29, P = 31 .....

ON= O + N = 29+27 =56

So, URGENT =U+R+G+E+N+T=41+35+13+9+27+39 =164

In a certain code, SEND is written as 2%*@ and DREAM is written as @ $%#5. How is MADE written in that code?
