MOST IMPORTANT verbal reasoning - 2 EXERCISES
The following question based on mathematical operations topic of verbal reasoning
(a) 8 ÷ 44 – 5 + 25 = 203
(b) 9 ÷ 64 - 2 × 6 = 54
(c) 56 + 12 × 34 – 12 = 102
(d) 112 × 44 – 12 + 10 = 46
The correct answers to the above question in:
Answer: (a)
8 ÷ 44 - 5 + 25 = 203
from the question by changing the symbols, we get
⇒ 8 + 44 × 5 - 25 = 203 (using VBODMAS rule)
⇒ 8 + 220 - 25 = 203
⇒ 228 - 25 = 203
⇒ 203 = 203
⇒ LHS = RHS.

Question : 1
If A = '+', B = ‘-‘, C = '×' and D = '÷', then which of the following equations is correct?
a) 8 B 6 D A 4 C 3 = 15
b) 9 C 9 B 9 D A 9 = 17
c) 3 A 3 B 3 C 3 A 3 D 3 = 41
d) 8 A 8 B 8 C 8 = - 48
Answer »Answer: (d)
From option (d),
8 A 8 B 8 C 8 = - 48
from the question by changing the symbols, we get
⇒ 8 + 8 - 8 × 8 = - 48
⇒ 8 + 8 - 64 = - 48 (using VBODMAS rule)
⇒ 16 - 64 = - 48
⇒ - 48 = - 48.
Therefore LHS = RHS.
So option (d) is correct.
Question : 2
If > denotes +, < denotes -, + denotes ÷, ^ denotes ×, - denotes =, × denotes > and = denotes <, choose the correct statement of the following.
a) 28 + 4 ^ 2 = 6 ^ 4 + 2
b) 13 > 7 < 6 + 2 = 3 ^ 4
c) 9 > 5 > 4 – 18 + 9 > 16
d) 9 < 3 < 2 > 1 × 8 ^ 2
Answer »Answer: (c)
From option (c),
9 > 5 > 4 - 18 + 9 > 16
By interchanging the signs,
9 + 5 + 4 = 18 ÷ 9 + 16 (using VBODMAS rule)
⇒ 18 = 18
Thus, option (c) is correct.
Question : 3
If ‘T' means (×), 'U' means (-), 'X' means (÷) and W means (+), then what will be the value of the following expression. (50 X 2) W (28 T 4)
a) 142
b) 158
c) 137
d) 163
Answer »Answer: (c)
Given expression, (50 × 2) W (28 T 4)
After interchanging the letters with symbols, we get
(50 ÷ 2) + (28 × 4) = 25 + 112 (using VBODMAS rule)
= 137
Question : 4

b) 5
c) 7
d) 9
e) None of these
Answer »Answer: (b)
According to the question,
? = 15 B 3 C 24 A 12 D 2
from the question by changing the symbols, we get
= 15 ÷ 3 +24 - 12 × 2 (using VBODMAS rule)
= 5 + 24 -12 × 2
= 5+ 24 - 24 = 5
Question : 5
If A means '×' B means ‘÷' C means '-' and D means ‘+', then 4 D 16 A 5 B 8 C 5 = ?
a) 9
b) 16
c) 13
d) 75
e) None of these
Answer »Answer: (a)
According to the question,
? = 4 D 16 A 5 B 8 C 5
from the question by changing the symbols, we get
= 4 + 16 × 5 ÷ 8 - 5 (using VBODMAS rule)
= 4 + 16 × 0.625 - 5
= 4 + 10 - 5
= 14 - 5 = 9
Question : 6
A means ‘+', B means '-' C means ‘×' and D means ÷, then 18 C 14 A 6 B 16 D 4 =?
a) 254
b) 238
c) 188
d) 258
e) None of these
Answer »Answer: (a)
According to the question,
? = 18 C 14 A 6 B 16 D 4
from the question by changing the symbols, we get
= 18 × 14 + 6 - 16 ÷ 4 (using VBODMAS rule)
= 18 × 14 + 6 - 4
= 252 + 6 - 4
= 258 - 4 = 254
