Question : 1
If '÷' means addition and '×' means subtraction, then (15 × 9) ÷ (12 × 4) × (4 ÷ 4) is equal to
a) 96
b) 6
c) $3/128$
d) $143/8$
Answer »Answer: (b)
According to the question,
Required answer = (15 × 9) ÷ (12 × 4) × (4 ÷ 4)
from the question by changing the symbols, we get
= (15 - 9) + (12 - 4) - (4 + 4) (using VBODMAS rule)
= 6 + 8 - 8
= 6
Question : 2
If A means ‘-’, B means '+', C means 'x', and D means '÷', then 32 D 4 B 7 C 2 A 6
a) 18
b) 24
c) 36
d) 16
e) 14
Answer »Answer: (d)
According to the question,
32 D 4 B 7 C 2 A 6
from the question by changing the alphabets, we get
= 32 ÷ 4 + 7 x 2 - 6 (using VBODMAS rule)
= 8 + 7 x 2 - 6
= 8 + 14 - 6
= 22 - 6 = 16
Question : 3
If K denotes ‘x', 'B' denotes ‘÷', ‘T’ denotes ‘-’ and 'M' denotes '+', then 40 B 8 T 6 M 3 K 4 = ?
a) 19
b) 11
c) -31
d) 23
e) None of these
Answer »Answer: (b)
According to the question,
40 B 8 T 6 M 3 K 4 = ?
from the question by changing the alphabets, we get
⇒ 40 ÷ 8 - 6 + 3 x 4 = ? (using VBODMAS rule)
⇒ 5 - 6 + 12 = ?
⇒ 17 - 6 = ?
Therefore ? = 11
Question : 4
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 : 5
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 : 6
If '+’ means subtraction, ‘÷’ means addition, ‘-‘ means multiplication and '×' means division, then which of the following equation is correct?
a) 8 ÷ 44 – 5 + 25 = 203
b) 9 ÷ 64 - 2 × 6 = 54
c) 56 + 12 × 34 – 12 = 102
d) 112 × 44 – 12 + 10 = 46
Answer »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.
Therefore the option (a) is correct.
