Test: Mathematical Operations - 2 - Question 1

If + stands for x, - for ÷, x for – and ÷ for +, find the value of 26 + 74 – 4 × 5 ÷ 2.

Detailed Solution for Test: Mathematical Operations - 2 - Question 1

Using the correct symbols, we have:
Given expression = 26 × 74 ÷ 4 – 5 + 2 = 26 × 37/2 - 5 + 2
= 13 × 37 - 5 + 2 = 481 - 5 + 2 = 478.

Test: Mathematical Operations - 2 - Question 2

If + means ÷, ÷ means -, - means x, x means +, then 12 + 6 ÷ 3 - 2 × 8 = ?

Detailed Solution for Test: Mathematical Operations - 2 - Question 2

Using the correct symbols, we have :

Given expression = 12 ÷ 6 – 3 × 2 + 8 = 2 – 6 + 8 = 10 – 6 = 4.

Test: Mathematical Operations - 2 - Question 3

If ‘when’ means ‘x’, ‘you’ means ‘÷’, ‘come’ means ‘-’ and ‘will’ means ‘+’, then what will be the value of “8 when 12 will 16 you 2 come 10”?

Detailed Solution for Test: Mathematical Operations - 2 - Question 3

Using the correct symbols, we have :

Given expression = 8 × 12 + 16 ÷ 2 - 10 = 96 + 8 - 10 = 104 - 10 = 94.

Test: Mathematical Operations - 2 - Question 4

If ‘+’ means ‘minus’, ‘x’ means ‘divided by’, ‘÷’ means ‘plus’ and ‘-’, means ‘multiplied by’, then which of the following will be the value of the expression 252 × 9 - 5 + 32 ÷ 92?

Detailed Solution for Test: Mathematical Operations - 2 - Question 4

Putting the proper signs in the given expression, we get :
Given Expression = 252 ÷ 9 × 5 - 32 + 92 = 28 × 5 - 32 + 92
= 140 - 32 + 92 = 232 - 32 = 200.

Test: Mathematical Operations - 2 - Question 5

If ‘+’ means ‘divide by’, ‘-’ means ‘added to’, ‘x’ means ‘subtracted from’ and ‘÷’ means ‘multiplied by’, then what is the value of 24 ÷ 12 - 18 + 9?

Detailed Solution for Test: Mathematical Operations - 2 - Question 5

Using the correct symbols, we have : Given expression = 24 × 12 + 18 ÷ 9 = 288 + 2 = 290.

Test: Mathematical Operations - 2 - Question 6

If + means x, x means -, ÷ means + and - means ÷, then which of the following gives the result of 175 - 25 ÷ 5 + 20 × 3 + 10?

Detailed Solution for Test: Mathematical Operations - 2 - Question 6

Using the proper signs in the given expression,

we get 175 ÷ 25 + 5 × 20 - 3 × 10 = 7 + 5 × 20 - 3 × 10 = 7 + 100 - 30
= 107 - 30 = 77.

Test: Mathematical Operations - 2 - Question 7

(bc + de) × ab is equal to

Detailed Solution for Test: Mathematical Operations - 2 - Question 7

Given expression = (23 + 45) × 12 = 68 × 12 = 816.

Test: Mathematical Operations - 2 - Question 8

If - means ÷, + means x, ÷ means -, x means +, then which of the following equations is correct?

Detailed Solution for Test: Mathematical Operations - 2 - Question 8

Using the proper notations in (a), we get the statement as
52 - 4 × 5 + 8 ÷ 2 = 52 - 4 × 5 + 4 = 52 – 20 + 4
= 56 - 20 = 36.

Test: Mathematical Operations - 2 - Question 9

In each of the following questions, the two expressions on either side of the sign (=) will have the same value if two terms on either side or on the same side are interchanged.
5 + 3 × 6 - 4 ÷ 2 = 4 × 3 - 10 ÷ 2 + 7

Detailed Solution for Test: Mathematical Operations - 2 - Question 9

On interchanging 6 and 4 on L.H.S., we get the statement as :

5 + 3 × 4 - 6 ÷ 2 = 4 × 3 - 10 ÷ 2 + 7 or 5 + 12 - 3 = 12 - 5 + 7 = or 14 = 14 which is true.

Test: Mathematical Operations - 2 - Question 10

In each of the following questions, the two expressions on either side of the sign (=) will have the same value if two terms on either side or on the same side are interchanged.
8 ÷ 2 × 5 - 11 + 9 = 6 × 2 – 5 + 4 ÷ 2

Detailed Solution for Test: Mathematical Operations - 2 - Question 10

On interchanging 6 and 4 on L.H.S., we get the statement as :

8 ÷ 2 × 5 – 11 + 6 = 9 × 2 – 5 + 4 ÷ 2 or 4 × 5 – 11 + 6 = 18 – 5 + 2 or 15
= 15, which is true.
