Question 4

A shopkeeper marks up his wares by 80% and offers 20% discount. What will be the selling price (in Rs) if the cost price is Rs 450?

Accepted Answer

Marked price is 180% of CP: 450 × 1.8 = 810. After a 20% discount, the selling price becomes 80% of MP: 810 × 0.8 = 648.

Question 5

Akarsh's birthday is on Saturday 29th July. On what day of the week will be Ojas's Birthday in the same year if Ojas was born on 12th August?

Accepted Answer

July has 31 days, so 2 days remain. Add 12 days of August: 2 + 12 = 14 days. 14 divided by 7 leaves 0 odd days. Thus, the day remains Saturday.

Question 6

The side BC of ΔABC is produced to D. If ∠ACD = 114° and ∠ABC= (1/2)∠BAC, then what is the value (in degrees) of ∠BAC?

Accepted Answer

Using the exterior angle theorem, ∠ACD = ∠ABC + ∠BAC. Let ∠BAC = 2x, so ∠ABC = x. Thus, 3x = 114°, giving x = 38°. Therefore, ∠BAC = 2x = 76°.

Question 7

After two successive discounts of 20% and 35%, an article is sold for Rs 50700. What is the marked price (in Rs) of the article?

Accepted Answer

Let Marked Price be MP. Selling Price = MP × (1 - 0.20) × (1 - 0.35) = MP × 0.80 × 0.65 = 0.52 MP. So, 0.52 MP = 50700, which gives MP = 97500.

Question 8

Who invented the hot air balloon?

Accepted Answer

The hot air balloon was invented by the Montgolfier brothers, Joseph-Michel and Jacques-Étienne, in 1783 in France. It was the first successful human-carrying flight technology.

Question 9

A and B have to type a book together containing 120 pages. A takes 9 hrs to type 36 pages and B takes 5 hrs to type 40 pages. A typed first 60 pages alone and the last 60 pages were typed by A and B together. How much time (in hours) will be taken to type the complete book?

Accepted Answer

A's rate is 4 pages/hr and B's is 8 pages/hr. A takes 15 hours for the first 60 pages. Together, they type 12 pages/hr, taking 5 hours for the rest. Total time = 15 + 5 = 20 hours.

Question 10

What is the simplified value of [(sec3x – tan3x)/(sec x – tan x)] – 2 tan2x – sec x tan x?

Accepted Answer

Use the a³-b³ formula to get sec²x + sec x tan x + tan²x. Subtracting 2tan²x and sec x tan x leaves sec²x - tan²x, which equals 1.

Question 11

If a retailer offers a discount of 20% on the marked price of his goods and thus ends up selling at cost price, what was the % mark up?

Accepted Answer

Let CP = 100. Since SP = CP, SP = 100. A 20% discount means SP is 80% of MP. So, 0.8 × MP = 100, giving MP = 125. Markup is 25%.

Question 12

If the price of pen decreases by 20%, then a man can buy 10 more pens for Rs 100. What is the new price (in Rs) of each pen?

Accepted Answer

A 20% decrease on Rs 100 saves Rs 20. This saved amount is used to buy the 10 extra pens. Therefore, the new price per pen is 20 / 10 = Rs 2.

Question 13

Arrange the given words in the sequence in which they occur in the dictionary. 1. Globe 2. Group 3. Glitch 4. Gap 5. Glade 1. Globe 2. Group 3. Glitch 4. Gap 5. Glade

Accepted Answer

Compare letters alphabetically. 'Gap' comes first. Among 'Gl' words, 'Glade' (a), 'Glitch' (i), and 'Globe' (o) follow in order. 'Group' (r) is last. Sequence: 4, 5, 3, 1, 2.

Question 14

X and Y both start from a same point. X walks 17 m West, then turns to his right and walks 13 m. At the same time, Y walks 9 m North, then turns East and walks 7 m, then turns to his left and walks 4 m. Where is Y now with respect to the position of X?

Accepted Answer

X's final position is 17m West and 13m North. Y's final position is 7m East and 13m North (9+4). Since both are 13m North, Y is 17 + 7 = 24m East of X.

Question 15

Ratio of present ages of Pankaj and Punit is 5 : 6 and the sum of their ages is 33 years. What will be the difference (in years) of their ages?

Accepted Answer

The sum of the ratio parts is 5 + 6 = 11. Since 11 parts equal 33 years, 1 part equals 3 years. The difference in their ratio is 6 - 5 = 1 part, which is 3 years.

Question 16

What is the difference in the average number of people living per 1,000 sq km in countries E and F?

Accepted Answer

Find the population density (people per 1,000 sq km) for countries E and F from the given chart or table. Subtracting the two values gives the exact difference of 2500.

Question 17

If a3 + b3 = 152 and a + b = 8, then what is the value of ab?

Accepted Answer

Use the formula a³ + b³ = (a+b)((a+b)² - 3ab). Substituting the values gives 152 = 8(64 - 3ab). Simplifying this yields 19 = 64 - 3ab, so 3ab = 45, meaning ab = 15.

Question 18

Name the Commission that came to India in 1928 to reform India's constitutional system.

Accepted Answer

The Simon Commission, officially the Indian Statutory Commission, arrived in India in 1928 to study constitutional reform. It was widely boycotted because it had no Indian members.

Question 19

What is the total number of visas issued from 2012 to 2015?

Accepted Answer

Simply add the number of visas issued in the years 2012, 2013, 2014, and 2015 from the provided data chart to get the total sum of 13000.

Question 20

Δ XYZ is right angled at Y. If m∠Z = 60°, then what is the value of (1/√2) Sec X?

Accepted Answer

Since ∠Y = 90° and ∠Z = 60°, ∠X must be 30°. Sec 30° is 2/√3. Multiplying by 1/√2 gives 2/√6.
