Question : 1
If '×' stands for '+', ÷ stands for '-', '-' stands for '×' and '+' stands for '÷', then find the value of following equation. 54 ÷ 16 - 3 × 6 + 2 = ?
a) 9
b) 12
c) 8
d) 15
Answer »Answer: (a)
According to the question,
? = 54 ÷ 16 - 3 × 6 + 2
from the question by changing the symbols, we get
= 54 - 16 × 3 + 6 ÷ 2 (using VBODMAS rule)
= 54 - 16 × 3 + 3
= 54 - 48 + 3
= 6 + 3 = 9
Question : 2
If ‘-‘ stands for 'addition', '÷’ for 'multiplication', ‘×’ for 'subtraction' and ‘+' for 'division', then which of the following is correct?
a) 25 × 12 - 14 ÷ 4 + 6 = 16
b) 25 – 12 + 14 ÷ 2 × 4 = 15
c) 25 – 15 + 5 ÷ 4 × 16 = 21
d) 25 + 11 – 4 ÷ 10 × 6 = 20
Answer »Answer: (c)
From option (c),
25 + 15 ÷ 5 × 4 - 16 = 21 (using VBODMAS rule)
⇒ 25 + 3 × 4 - 16 = 21
⇒ 25 + 12 - 16 = 21
⇒ 37 - 16 = 21
⇒ 21 = 21
LHS = RHS
So, option (c) is correct.
Question : 3
If ‘<’ means 'minus', ‘>' means ‘plus', '=’ means 'multiplied by' and '#' means 'divided by’, then what would be the value of 27 > 81 # 9 <6?
a) 6
b) 33
c) 36
d) 54
e) None of these
Answer »Answer: (e)
Using the correct symbols,
we have: Given expression as
= 27+ 81 ÷ 9 – 6
= 27 + 9 - 6
= 36 - 6 = 30.
Question : 4
If '×' means subtraction, '+' means multiplication and '-' means addition, then find the value of following equation. 12 + (3 × 1) + 4 - 1 = ?
a) 98
b) 75
c) 85
d) 97
Answer »Answer: (d)
According to the question,
? = 12 + (3 × 1) + 4 - 1
from the question by changing the symbols, we get
= 12 × (3 - 1) × 4 + 1 (using VBODMAS rule)
= 12 × 2 × 4 + 1
= 96 + 1 = 97
Question : 5
If '-' stands for '÷' ‘+’ stands for ‘x', '÷' for ‘-‘ for ‘x' for '+', which one of the following equations in correct?
a) 30 – 6 + 5 x 4 ÷2 = 27
b) 30 + 6 -5 ÷ 4 x 2= 30
c) 30 x 6 ÷ 5 – 4 + 2 = 32
d) 30 ÷6 x 5+ 4 -2 = 40
Answer »Answer: (a)
- ⇒ ÷, + ⇒ x, ÷ ⇒ x, - ⇒ +,
From option (a),
30 - 6 + 5 x 4 ÷ 2 = 27
⇒ 30 ÷ 6 x 5 + 4 - 2 = 27
⇒ 5 x 5 + 4 - 2 = 27
⇒ 25 + 4 - 2 = 27
Therefore 27 = 27
Question : 6
If ‘-’ stands for division, '+' for multiplication, '÷' for subtraction and ‘x' for addition, then which one of the following equations is correct?
a) 19 + 5 - 4 x 2 ÷ 4 =11
b) 19 x 5 – 4 ÷ 2 + 4 =16
c) 19 ÷ 5 + 4 – 2 x 4 = 13
d) 19 ÷ 5 + 4 -2 ÷ 4= 20
Answer »Answer: (c)
- ⇒ ÷, + ⇒ x, ÷ ⇒ x, - ⇒ +,
From option (a), 19 + 5 - 4 x 2 ÷ 4 = 11
⇒ 19 x 5 ÷ 4 + 2 - 4 = 11
⇒ 95/4 + 2 - 4 ≠ 11
From option (b),
19 x 5 - 4 ÷ 2 + 4 = 16
⇒ 19 + 5 ÷ 4 - 2 x 4 = 16
⇒ 19 + 5/4 - 8 ≠ 16
From option (c),
19 ÷ 5 + 4 - 2 x 4 = 13
⇒ 19 - 5 x 4 ÷ 2 + 4 = 13
⇒ 19 - 5 x 2 + 4 = 13
⇒ 19 - 10 + 4 = 13
Therefore 13 = 13
As,we got our answer, there is no need to check option (d).
