5.Some equations have been solved on the basis of a certain pattern. Find the correct answer for the unsolved equation in the basic.

a)8436

b)2184

c)3180

d)2526

a)8436

Answer

In the given equations

5 x 3 x 2 = 1510

First number is multiplied with second number and gives 15 then First number is multiplied with Third number and gives 10

Similarly

12 x 7 = 84

12 x 3= 36

Therefore 12 x 7 x 3 =8436

6) In the following questions, the symbols @, ©, $, % and # are used with the following meaning as illustrated below:

‘P$Q’ means ‘P is not greater than Q’

‘P@Q’ means ‘P is neither smaller than nor equal to Q’

‘P#Q’ means ‘P is not smaller than Q’

‘P©Q’ means ‘P is neither greater nor equal to Q’

‘P%Q’ means ‘P is neither smaller nor greater than Q’

Statements:

B%J, J@K, K©T, T©F

Conclusions:

I) F@K

II) B@K

III) B@F

a) I and II are true

b) I and III are true

c) II and III are true

d) All are true

e) None is true

a) I and II are true

Answer

According to the question,

B%J B=J (I)

J@K J>K (II)

K©T K<T (III

T$F TF (IV)

On combining the statements (I), (II), (III) and(IV) we get

B=J>K<TF

Conclusions:

I) F@K F>K (true)
II) B@K B>K (true)

III) B@F B>F (false)

So, it is clear that both Conclusions I and II are true

7) In the following questions, the symbols @, ©, $, % and # are used with the following meaning as illustrated below:

‘P$Q’ means ‘P is not greater than Q’

‘P@Q’ means ‘P is neither smaller than nor equal to Q’

‘P#Q’ means ‘P is not smaller than Q’

‘P©Q’ means ‘P is neither greater nor equal to Q’

‘P%Q’ means ‘P is neither smaller nor greater than Q’

Statements:

H$M, M#T, T@D, D©R

Conclusions:

I) D©M

II) R@M

III) H$T

a) None is true

b) Only I is true

c) Only II is true

d) Only III is true

e) All I, II, III are true

b) Only I is true

Answer

H$M HM (I)

M#T MT (II)

T@D T>D (III)

D©R D<R (IV)

On combining the statements (I), (II), (III) and (IV) we get

HMT>D<R

Conclusions:

I) D©M D<M (true)
II) R@M R>M (false)

III) H$T HT (false)

So, it clear that only Conclusion I is true.

‘P$Q’ means ‘P is not greater than Q’

‘P@Q’ means ‘P is neither smaller than nor equal to Q’

‘P#Q’ means ‘P is not smaller than Q’

‘P©Q’ means ‘P is neither greater nor equal to Q’

‘P%Q’ means ‘P is neither smaller nor greater than Q’

Statements:

W©B, B%V, V$R, R@K

Conclusions:

I) K©B

II) R#B

III) V@W

a) I and II are true

b) I and III are true

c) II and III are true

d) All I, II and III are true

e) None is true

c) II and III are true

Answer

According to the question

On combining the statements (I), (II), (III) and (IV) we get

W<B=VR>K

Conclusions:

II) R#B RB (true)

III) V@W V>W (true)

So it clear that both Conclusions II and III are true

‘P$Q’ means ‘P is not greater than Q’

‘P@Q’ means ‘P is neither smaller than nor equal to Q’

‘P#Q’ means ‘P is not smaller than Q’

‘P%Q’ means ‘P is neither smaller nor greater than Q’

Statements:

Conclusions:

I) R@J

II) J@N

III) B@D

a) None is true

b) Only I is true

c) Only II is true

d) Only II and III are true

c) Only II is true

Answer

According to the question

On combining the statements (I), (II), (III) and (IV) we get

R>N<DJB

Conclusions:

I) R@J R>J(false)

II) J@N J>N (true)

III) B@D B>D (false)

So, it is clear that only Conclusion II is true

‘P$Q’ means ‘P is not greater than Q’

‘P@Q’ means ‘P is neither smaller than nor equal to Q’

‘P#Q’ means ‘P is not smaller than Q’

‘P%Q’ means ‘P is neither smaller nor greater than Q’

Statements:

D#K, K@T, T$M, M%J

Conclusions:

I) J@T

II) J%T

III) D@T

a) Only I is true

b) Only II is true

c) Either I or II is true

d) Either I or II and III are true

e) None is true

Click Here to View Answer

d) Either I or II and III are true

Answer

On combining the statements (I), (II), (III) and (IV), we get

DK>TM=J

Conclusions:

I) J@T J>T

II) J%T J=T (Either I or II is true)

III) D@T D>T (true)

So it is clear that either Conclusions I or II and III are true.
