A mirage is a naturally occurring optical illusion or phenomenon in which light rays are bent due to refraction in layers of air of varying density. The image usually is upside down, enhancing the illusion that the sky image seen in the distance is really a water or oil puddle acting as a mirror.

There is a high content of calcium carbonate in mussel andoyster shells, which can be used in the formulation of medicine, in construction or as filler in polymer materials.

A fluorescent lamp or fluorescent tube is a gas-discharge lamp that uses electricity to excite mercury vapour. it contains mercury vapour and argon. The excited mercury atoms produce short-wave ultraviolet light that then causes a phosphor to fluoresce, producing visible light. A fluorescent lamp converts electrical power into useful light more efficiently than an incandescent lamp.

The man in the photo is the son of the sister of Bajpai. Hence, Bajpai is the maternal uncle of the man in the photograph.

Cat, Dog, Tiger and Lion are carnivores, while Elephant is a herbivore.

So, INDIAN = I + N + D + I + A + N
= 17 + 27 + 7 + 17 + 1 + 27 = 96.

Clearly, vowels A, E, I, O, U are coded as 1, 2, 3, 4, 5 respectively. Each of the consonants in the word is moved one step forward to give the corresponding letter of the code. So, the code for ACID becomes 1D3E.

The exports are more than the imports imply that the ratio of value of imports to exports is less than 1.

Now, this ratio is less than 1 in years 1995, 1996, 1997 and 2000.

Thus, there are four such years.

The interest he pays per year would be 36 + 55 = 91. Thus, in 4 years the interest would amount to Rs. 364.

 100/12 = 8.33%

3/14 of 5/13 of 6/7 of 3822 = 3 * 5 * 6 * 3 = 270

So Option C is correct

69.69 – 51.54 = 18.15
18.15 + 73.65 = 91.80
91.80 – 32.42 = 59.38

So Option D is correct

HCF (427 – 3, 900 – 8) (424, 892) = 4

Answer – d) 15 Explanation : alcohol = 30*2/5 = 12 and water = 18 litres (12 + x)/(30 +x) = 60/100, we will get x = 15

Answer – b) 100 Explanation : (20/100)*t*t = 2000 (total students = t)

Efficiency of A + B = 33.33% = (100 / 3)

Ratio of efficiency of A and B = 3 : 1
∴ Efficiency of A = 
∴ Number of days taken by A = 4 = 100 /25
Alternatively :

∴ Difference in days = 2x = 8
 ► ⇒ x = 4 and 3x = 12

Therefore number of days taken by A, working alone = 4 days
Alternatively : 

Now, you can use the options, or solve the equations to get the value of x which is equal to 4.

Let B be the cost of a banana and A be the cost of an apple.
Let x be the total cost of 8 bananas and 6 apples.
According to the question,
8B + 6A = x
8.8B + 5.4A = x
⇒ 0.8B = 0.6A
B/A = 3/4

Let G be the number of goals scored and p be the number of international players.
G α p²
∴ G = kp²
When 4 players play, G₁ = k × 4² = 16k
When 6 players play, G₂ = k × 6² = 36k
G₂ - G₁ = 5 goals
∴ 5 = k (36 - 16) or k = ¼
When 8 players play,
G = (1/4) × 8² = 16

Cost of running a printing machine for 10000 copies

Cost of setting of 5000 copies = Rs. 2000

Cost of setting of other 5000 copies 

Other cost of 10,000 copies

Total cost price of 10,000 copies = 3200 + (2000 + 1500) + 6000 = Rs. 12,700
Selling price of 8260 copies = 8260 × 1.75 = Rs. 14,455

Net amount earned from advertisement = Total profit - Selling price of 8260 copies
= 16,510 - 14,455 = Rs. 2055

We cut the can along a line passing through P, Q and R, and we stretch out the tank so that its side is in the shape of a rectangle. Then, P, Q and R appear as points on two opposite edges of the rectangle. The length of the rectangle is 2π × 2 = 4π and its height is 6. We draw two such rectangles beside each other and indicate where P, Q and R lie along the edges, as shown below.

The shortest path from P to Q to R is indicated above (the first time around the tank is indicated by the line segment from P to Q, and the second time around the tank is indicated by the line segment from Q to R). Given that the vertical distance from P to Q is 4 feet and the vertical distance from Q to R is 2 feet, we get from two applications of the Pythagorean theorem that the length of the shortest path is
