  1. 4%
  2. 5%
  3. 6%
  4. 20%
  5. None of these

Answer (Detailed Solution Below)

Option 1 : 4%

HTET TGT Quantitative Aptitude Questions Question 1 Detailed Solution

The correct answer is option 1.

Given:

The price of tea being increased by 20%, a man reduces his consumption by 20%. 

Calculation:

⇒ Let assume initial price of tea = Rs. 100 per kg

And man consumption was 1 kg.

So, Initial expenses for tea = 100 x 1 = Rs.100

Now price is increased by 20% = 120% of 100 = Rs. 120 per kg

And consumption is reduced by 20% = 80% of 1 kg = 0.8 kg

Now, man expenses for tea = 120 x 0.8 = Rs. 96

Percentage reduction in expenses = 

 = - 4%

So, his expenses for tea  will be decreased by 4%.

HTET TGT Quantitative Aptitude Questions Question 2:

An engineering student has to secure 15% marks to pass. He gets 55 marks and fails by 20 marks. Find his maximum marks.

  1. 300
  2. 600
  3. 500
  4. 200
  5. 400

Answer (Detailed Solution Below)

Option 3 : 500

HTET TGT Quantitative Aptitude Questions Question 2 Detailed Solution

Given:

An engineering student has to secure 15% marks to pass.

A student gets 55 marks and fails by 20 marks.

Calculation:

Let the total marks be x

Passing marks = x × 15%

Passing marks = 15x/100      ----(1)

According to the question,

Passing marks = 55 + 20 = 75      ----(2)

From equation (1) and (2) we get,

⇒ 15x/100 = 75

⇒ x = 7500/15

⇒ x = 500

∴ The maximum marks of the student is 500.

Shortcut Trick

Passing percentage = 15%

Passing marks = 55 + 20 = 75

Maximum marks = (75/15) × 100 = 500

∴ The maximum marks of the student is 500.

HTET TGT Quantitative Aptitude Questions Question 3:

An article on cost price Rs. 6000 is marked at Rs. 7800. After allowing a discount of x percent a profit of 4% is made. The value of x is

  1. 10%
  2. 20%
  3. 24%
  4. 30%
  5. 48%

Answer (Detailed Solution Below)

Option 2 : 20%

HTET TGT Quantitative Aptitude Questions Question 3 Detailed Solution

GIVEN:

The cost price of an article = Rs. 6000

MP of an article = Rs. 7800

Profit percentage = 4%

CALCULATION:

The cost price of the article = Rs. 6000

Profit percentage = 4%

SP of the article

⇒ CP × (100 + Profit%)/100

⇒ 6000 × 104/100 = Rs. 6240

∵ Discount = MP – SP

= 7800 – 6240 = Rs. 1560

Let the discount percentage = x%

∴ (7800 × x)/100 = 1560

= x = 1560/78 = 20%

∴ Discount percent = 20%

Alternate Method

(100 – Discount%)/ (100 + Profit%) = CP/MP

Ratio of CP and MP = 6000/7800 = 10/13

∵ (100 – Discount%)/ (100 + Profit%) = CP/MP

⇒ (100 – x)/(100 + 4) = 10/13

⇒ 1300 – 13x = 1000 + 40

⇒ 1300 – 1040 = 13x

⇒ 260 = 13x

x = 20%

Discount% = 20%
