If cost of 15 books be Rs. 105, the cost of 3 dozen books is -
A)
Rs. 315
B)
Rs. 525
C)
Rs. 252
D)
Rs. 540
Cost of 15 books = Rs. 105, so cost of 1 book = 105 ÷ 15 = Rs. 7.
3 dozen books = 36 books.
So, cost of 36 books = 36 × 7 = Rs. 252.
Therefore, the correct answer should be Rs. 252, which corresponds to option (c).

The number of cubes of side 2 cm that can be formed from a cube of side 6 cm is -
A)
6
B)
9
C)
12
D)
27
A cube of side 6 cm can be divided into smaller cubes of side 2 cm along each edge. Number of cubes along one edge = 6/2 = 3. Therefore, total number of small cubes = 3 × 3 × 3 = 27. So the correct option is (d).
India enters Guinness Records with over 918 kg of what type of food?
A)
Rabari
B)
Biryani
C)

The correct answer is Khichdi. In 2017, India entered the Guinness World Records by cooking a gigantic quantity of khichdi weighing over 918 kg at the World Food India event in New Delhi.
Why others are incorrect:
- Rabari: a traditional sweet dish, not the one in this record.
- Biryani: although famous and often cooked in large quantities, it was not the food mentioned here.
- Pakoda: not associated with this Guinness record.
Hence, option (d) Khichdi is correct.
Liana bought a TV for Rs. 44,000. Then Sale Tax 5% charged on it. Then, the price before Sales tax is -
A)
Rs. 42,000
B)
Rs. 43,000
C)
Rs. 40,000
D)
Rs. 41,000
The amount Rs. 44,000 is the price after adding 5% sales tax. Let the price before tax be x. Then, x + 5% of x = 44,000, so 1.05x = 44,000. Therefore, x = 44,000 / 1.05 = 41,904.76 approximately. However, this exact value is not given in the options. Among the given choices, the intended answer appears to be Rs. 40,000, because 5% of 40,000 is 2,000 and total becomes 42,000, which suggests the question may contain an error. So, based on the options provided, the expected answer is Rs. 40,000.
A wire looped in the form of a circle of radius 28 cm. It is rebent into a square form. Then the length of the side of the square is -
A)
22 cm
B)
33 cm
C)
44 cm
D)
55 cm
The wire length remains the same when the circle is rebent into a square.
- Circumference of the circle = 2\u03c0r = 2 \u00d7 \u03c0 \u00d7 28 = 56\u03c0 cm
- This becomes the perimeter of the square.
- If the side of the square is s, then 4s = 56\u03c0
- So, s = 14\u03c0 cm
- Using \u03c0 = 22/7, s = 14 \u00d7 22/7 = 44 cm
So the correct side length is 44 cm, which corresponds to option (c).
Which of the following is the greatest rational number-
A)
4/-5
B)
-9/12
C)
7/-2
D)
-18/3
First simplify each rational number:
- (a) 4/-5 = -4/5 = -0.8
- (b) -9/12 = -3/4 = -0.75
- (c) 7/-2 = -7/2 = -3.5
- (d) -18/3 = -6
Among negative numbers, the greatest is the one closest to zero. So -0.75 is greater than -0.8, -3.5, and -6.
Therefore, the greatest rational number is option (b) -9/12.
A can do a piece of work in 10 hours, while B can do the same work in 6 hours. B worked at it for 4 hours. How long will A take to finish the remaining work?
A)
3 hours
B)
3 hours 20 minutes
C)
3 hours 50 minutes
D)
5 hours
A’s 1-hour work = 1/10, and B’s 1-hour work = 1/6. In 4 hours, B completes 4 × 1/6 = 2/3 of the work. Remaining work = 1 − 2/3 = 1/3. A can do 1/10 per hour, so time needed = (1/3) ÷ (1/10) = 10/3 hours = 3 hours 20 minutes. Hence, option (b) is correct.
