Question

Statements: U * Y, Y © R, R $\delta$ D

Conclusions:

I. D $\$$ Y
II. R @ U

• A. Only conclusion I is true.
• B. Only conclusion II is true.
• C. Neither conclusion I nor II is true.
• D. Both conclusions I and II are true.

Answer 1

The correct option is B

Only conclusion II is true.

From the given statements
U*Y means ‘U is smaller than Y’. So U < Y. (a)
Y© R means ‘Y is either smaller or equal to R’. So Y £ R (b)
R $\delta$ D means ‘R is not smaller than D’. So R ≥ D (c)
Combining all the equations, you get U < Y £ R ≥ D (d)
Now, for the given conclusions
D$\$$Y means ‘D is neither smaller nor greater than Y’. So D = Y. (i)
R@U means ‘R is neither smaller nor equal to U’. So R > U. (ii)
So only conclusion (ii) follows.
