Agniveer Vayu Mathematical Operation Questions

Q1. In a certain code language, ‘+’ represents ‘×’, ‘–’ represents ‘+’, ‘×’ represents ‘÷’ and ‘÷’ represents ‘–’. What is the answer to the following question?

12 × 6 ÷ 5 + 4 = ?

(a) 8

(b) –18

(d) 18

S1. Ans.(b)

Sol. According to the question,

+	–	×	÷
×	+	÷	–

⇒ ? = 12 × 6 ÷ 5 + 4

⇒ ? = 12 ÷ 6 – 5 × 4

⇒ ? = 2 – 20

∴ ? = -18

Q2. If “–” mean “divided by”, “+” means “multiplied by”, “÷” means “added to”, “×” means “subtracted from”, then 11 ÷ 6 – 2 + 5 × 3 = ?

(a) 17

(b) 21

(d) 26

S2. Ans.(c)

Sol.

–	÷	+	×
÷	+	×	–

? = 11 ÷ 6 – 2 + 5 × 3

⇒ ? = 11 + 6 ÷ 2 × 5 – 3

⇒ ? = 11 + 3 × 5 – 3

⇒ ? = 11 + 15 – 3

∴ ? = 26 – 3 = 23

Q3. In a certain code language, ‘+’ represents ‘×’, ‘–’ represents ‘+’, ‘×’ represents ‘÷’ and ‘÷’ represents ‘–’. What is the answer to the following question?

9 + 3 – 72 × 6 ÷ 3 = ?

(a) 46

(b) 21

(d) 36

S3. Ans.(d)

Sol. 9 + 3 – 72 × 6 ÷ 3 = ?

+	–	×	÷
×	+	÷	–

Changing signs according to question,

9 × 3 + 72 ÷ 6 – 3 = ?

⇒ 27 + 12 – 3 = ?

⇒ 39 – 3 = ?

∴ ? = 36

Q4. In a certain code language, ‘+’ represents ‘×’, ‘–’ represents ‘+’, ‘×’ represents ‘÷’ and ‘÷’ represents ‘–’. What is the answer to the following question?

60 × 5 + 3 ÷ 24 – 6 = ?

(a) 18

(b) 94

(d) 57

S4. Ans.(a)

Sol. 60 × 5 + 3 ÷ 24 – 6 = ?

+	–	×	÷
×	+	÷	–

Changing signs according to the question,

60 ÷ 5 × 3 – 24 + 6 = ?

⇒ 12 × 3 – 24 + 6 = ?

⇒ 36 – 24 + 6 = ?

⇒ 42 – 24 = ?

∴ ? = 18

Q5. In a certain code language, ‘+’ represents ‘×’, ‘–’ represents ‘+’, ‘×’ represents ‘÷’ and ‘÷’ represents ‘–’. What is the answer to the following question?

15 – 5 + 25 ÷ 10 = ?

(a) 22

(b) –4

(d) 130

S5. Ans.(d)

Sol. ? = 15 – 5 + 25 ÷ 10

= 15 + 5 × 25 – 10

= 15 +125 – 10 = 130

Q6. If ‘‘α’’ denotes ‘‘subtracted from’’, ‘‘β’’ denotes ‘‘multiplied by’’, ‘‘θ’’ denotes ‘‘added to’’ and ‘‘δ’’ denotes ‘‘divided by’’, then

10 θ 8 β 4 δ 8 α 9 = ?

(a) 7

(b) 5

(d) 11

S6. Ans.(b)

Sol.

α	β	θ	δ
–	×	+	÷

10 θ 8β 4δ 8α 9 = ?

⇒ 10 + 8 × ÷ 8 – 9 = ?

⇒ 10 + 8 × 1/2 – 9

⇒ 10 + 4 – 9 = ?

⇒ 14 – 9 = ?

∴ ? = 5

Q7. In a certain code language, ‘+’ represents ‘×’, ‘–’ represents ‘+’, ‘×’ represents ‘÷’ and ‘÷’ represents ‘–’. What is the answer to the following question?

45 × 5 + 2 – 20 = ?

(a) 17

(b) 81

(d) 64

S7. Ans.(c)

Sol. 45 × 5 + 2 – 20 = ?

+	–	×	÷
×	+	÷	–

Changing signs according to question,

45 ÷ 5 × 2 + 20 = ?

⇒ 9 × 2 + 20 = ?

⇒ 18 + 20 = ?

∴ ? = 38

Q8. In a certain code language, ‘+’ represents ‘×’, ‘–’ represents ‘+’, ‘×’ represents ‘÷’ and ‘÷’ represents ‘–’. What is the answer to the following question?

45 × 5 – 24 + 3 ÷ 80 = ?

(a) 100

(b) 52

(d) 82

S8. Ans.(c)

Sol. 45 × 5 – 24 + 3 ÷ 80 = ?

+	–	×	÷
×	+	÷	–

Changing signs according to question,

45 ÷ 5 + 24 × 3 – 80 = ?

⇒ 9 + 72 – 80 = ?

⇒ 81 – 80 = ?

? = 1

Q9. In a certain code language, ‘+’ represents ‘×’, ‘–’ represents ‘+’, ‘×’ represents ‘÷’ and ‘÷’ represents ‘–’. What is the answer to the following question?

80 + 2 ÷ 25 + 5 – 10 = ?

(a) 35

(b) 98

(d) 45

S9. Ans.(d)

Sol. 80 + 2 ÷ 25 + 5 – 10 = ?

+	–	×	÷
×	+	÷	–

⇒ 80 × 2 – 25 × 5 + 10 = ?

⇒ 160 – 125 + 10 = ?

⇒ 170 – 125 = ?

∴ ? = 45

Q10. In a certain code language, ‘+’ represents ‘×’, ‘–’ represents ‘+’, ‘×’ represents ‘÷’ and ‘÷’ represents ‘–’. What is the answer to the following question?

72 × 9 –14 + 2 = ?

(a) 20

(b) 86

(d) 36

S10. Ans.(d)

Sol. 72 × 9 – 14 + 2 = ?
