Q1. Which of the following symbols should replace the question mark (?) in the given expression in order to make the expressions P > B as well as T ≤ C definitely true?

P > C ? B ≥ N = T

(a) ≤

(b) >

(c) <

(d) ≥

(e) Either ≤ or <

S1. Ans.(d)

Sol. P > C ? B ≥ N = T

When we put  ≥ instead of ? sign then

P> C  ≥ B  ≥ N = T

In this expression P > B and T ≤ C both are true.

Q2. Which of the following should be placed in the blank spaces respectively (in the same order from left to right) in order to complete the given expression in such a manner that makes the expression C > N as well as E ≤ L definitely true?

C _ L _ O _ N _ E

(a) =, =, ≥, ≥

(b) >, ≥, =, >

(c) >, <, =, ≤

(d) >, =, =, ≥

(e) >, =, ≥, >

S2. Ans.(d)

Sol. C > L = O = N ≥ E

In this expression C > N and E ≤ L both are true.

Q3. Which of the following symbols should be placed in the blank spaces respectively (in the same order from left to right) in order to complete the given expression in such a manner that makes the expression A > N and U > E definitely false?

A _ O _ U _ N _ E

(a) <, <, >, =

(b) <, =, =, >

(c) <, =, =, <

(d) >, =, =, ≥

(e) >, >, =, <

S3. Ans.(c)

Sol. A < O = U = N < E

In this expression A> N and U > E both are false.

Q4. Which of the following symbols should be placed in the blank spaces respectively (in the same order from left to right) in order to complete the given expression in such a manner that makes the expression P > Q as well as R ≤ S definitely true?

P _ S _ T _ Q _ R

(a) =, =, ≥, ≥

(b) >, ≥, =, >

(c) >, <, =, ≤

(d) >, =, =, ≥

(e) >, =, ≥, >

S4. Ans.(d)

Sol. P > S = T = Q  ≥ R 

In this expression P > Q and R ≤ S both are true.

Q5. Which of the following symbols should be placed in the blank spaces respectively (in the same order from left to right) in order to complete the given expression in such a manner that makes the expression A > B and C > D definitely false?

A _ E _ C _ B _ D

(a) <, <, >, =

(b) <, =, =, >

(c) <, =, =, <

(d) >, =, =, ≥

(e) >, >, =, <

S5. Ans.(c)

Sol.  A < E = C = B < D

In this expression A > B and C > D both are false.
