Q-1) If '-‘ denotes addition, ‘+' denotes subtraction, ‘×' denotes division and ÷ denotes multiplication, then 7 -10 × 5 ÷ 6 + 4 =?
(a)
(b)
(c)
(d)
According to the question,
? = 7 - 10 × 5 ÷ 6 + 4
from the question by changing the symbols, we get
= 7 + 10 ÷ 5 × 6 - 4 (using VBODMAS rule)
=7 + 2 × 6 - 4
= (7 + 12) - 4
= 15
Q-2) If A means '×' B means ‘÷' C means '-' and D means ‘+', then 4 D 16 A 5 B 8 C 5 = ?
(a)
(b)
(c)
(d)
(e)
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
Q-3) If A means ‘-', B means '÷', C means ‘+' and D means '×', then 15 B 3 C 24 A 12 D 2 = ?
(a)
(b)
(c)
(d)
(e)
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
Q-4) If A = '+', B = ‘-‘, C = '×' and D = '÷', then 5 C 5 D 5 A 5 B 5 = ?
(a)
(b)
(c)
(d)
According to the question,
? = 5 C 5 D 5 A 5 B 5
from the question by changing the symbols, we get
= 5 × 5 ÷ 5 + 5 - 5 (using VBODMAS rule)
= 5 × 1 + 5 - 5
= 10 - 5 = 5
Q-5) If '×' stands for '+', ÷ stands for '-', '-' stands for '×' and '+' stands for '÷', then find the value of following equation. 54 ÷ 16 - 3 × 6 + 2 = ?
(a)
(b)
(c)
(d)
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
Q-6) If + means -, - means x, ÷ means + and x means ÷, then 15 - 3 + 10 x 5 ÷ 5 = ?
(a)
(b)
(c)
(d)
Using the correct symbols,
we have: Given expression
= 15 x 3- 10 ÷ 5 + 5 (using VBODMAS rule)
= 45 - 2 + 5
= 50 - 2 = 48.
Q-7) If x means +, + means ÷, – means x and ÷ means -, then 8 x 7 – 8 + 40 ÷ 2 =?
(a)
(b)
(c)
(d)
Using the correct symbols,
we have: Given expression
= 8 + 7 x 8 ÷ 40 - 2
= 8 + 7 x $1/8$ - 2
= 6 + = 6 + $1/5$
= $ 37/5$ = 7$2/5$
Q-8) If '×' means subtraction, '+' means multiplication and '-' means addition, then find the value of following equation. 12 + (3 × 1) + 4 - 1 = ?
(a)
(b)
(c)
(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
Q-9) If x means ÷, - means x, ÷ means + and + means -, then (3 - 15 ÷ 19) x 8 +6 =?
(a)
(b)
(c)
(d)
Using the correct symbols,
we have: Given expression
= (3 x 15 + 19) ÷ 8 - 6
