- 5. In this question, a word is represented by only one set of numbers as given in any one of the alternatives. The sets of numbers given in the alternatives are represented by two classes of alphabet as in two matrices given below. The columns and rows of Matrix I are numbered from 0 to 4 and that of Matrix II are numbered from 5 to 9. A letter from these matrices can be represented first by its row and next by its column, e.g., 'A' can be represented by 04, 12, etc., and 'R' can be represented by 55, 67, etc. Similarly, you have to identify the set for the word 'B E N T'.

Correct Answer: Only either I or III follows
Explanation:
All pins are bags (A) ? conversion ? Some bags are pins (I). All needles are bags + Some bags are pins = A + I = No conclusion Hence I and III do not follow by combination. However, they from an complementary E-I pair, either I or III follows. Again, All chalks are bags + conversion of all needles are bags = A + I = No conclusion Hence II do not follow.
Correct Answer: Only I and III follows
Explanation:
All buckets are tubs(A) ? conversion ? Some tubs are buckets (I) Hence II does not follow. All buckets are tubs + All tubs are drums A + A = A = All buckets are drums ? conversion ? Some drums are buckets + All buckets are drums = A + A + I + = Some drums are pots(I). Hence II follows.
Correct Answer: None follows
Explanation:
I-type statements can't be combined.
Correct Answer: Only either I or III & II follows
Explanation:
All pins are rods + Some rods are chains = A + I = No conclusion Hence I and II does not follow. However, the two a complementary I-E pair, Hence either I or III follows. Some rods are chains + All chains are Hammers = I + A + I = Some rods are hammers ? conversion ? Some hammers are rods (I). Hence III follows.
Correct Answer: 31, 22, 88, 58
Explanation:
From above given matrices I and II , we can see that
B ? 00, 13, 24, 31, 42
E ? 03, 11, 22, 34, 40
N ? 57, 69, 76, 88, 95
T ? 58, 65, 77, 89, 96
As shown in given figure , all the values for word BENT are matched in only option ( 3 ) for every letter . So , the set for the word BENT will be 31, 22, 88, 58 .From matrix , option ( 3 ) is correct .
Correct Answer: Only II and III follows
Explanation:
All flowers are trees + All trees are jungles = A + A = A = All flowers are jungles ? conversion ? Some jungles are flowers Hence III follows. All trees are jungle + No jungle is hill = A + E = E = No tree is hill. Hence III follows. All flowers are trees + No tree is hill. Hence II follows. All flowers are trees + No tree is hill = A + E = E = No flower is hill. Hence I follows.
Correct Answer:
Explanation:
All sofas are beds + All beds are mats = A + A = A = All sofas are mats ? conversion ? Some mats are sofas (I). Hence I follows. All tables are sofas + All sofas are beds = A + A = A = All tables are beds ? conversion ? Some beds are tables(I). Hence II follows. All tables are beds + All beds are mats = A + A = A = All tables are mats ? conversion ? Some mats are tables (I). Hence III follows.
Correct Answer: Only either II or III follow
Explanation:
I-type statements can't be combined no conclusion follow by combined But II and III make a complementary I-E pair, Hence either I or III follows.
Correct Answer: Only I and II follow
Explanation:
Some trees are houses + All houses are wheels = I + A = I = Some trees are wheels ? (I) conversion ? Some wheels are trees (I). Hence I follows. All flowers are tree ? (A) conversion ? Some trees are flowers (I). Hence II follows. But II and III can't, be combined as they are I -type statements Hence III does not follow.
Correct Answer: All follow
Explanation:
All windows are doors + All doors are boats = A + A = A = All windows are boats. Hence I follows. All buildings are doors + All doors are boats = A + A = A = All buildings are boats. Hence II follows. All doors are boats (A) ? conversion ? Some boats are doors(I). Hence III follows.
