(ii) 'P `div` Q' means 'P is sister of Q'.
(iii) 'P + Q' means 'P is brother of Q'.
(iv) 'P-Q' means 'P is father of Q'.
Which of the following means 'K is son of R' ?

Options

A. `R xx K`
B. R-K
C. `K + T xx R`
D. `R - J div K + M`

Answer

D

Explanation

Options (a) & (b):
`R xx K = R` is mother of K.
R - K = R is father of K.
[`because` The gender of K is not known]
So, both options are discarded.
Option (c) : K + T = K is brother of T.
T `xx` R = T is mother of R.
So, K is the maternal uncle of R.
Option (d) : R-J = R is father of J.
J + K = J is sister of K.
K + M = K is brother of M.
