From the analysis of graph the exports of Company Z are more than the average annual exports of Company Z (i.e., Rs. 85.71 crores) during the years 1994, 1995, 1996 and 1999, i.e., during 4 of the given years.

Halley’s Comet is visible from earth after about 76 years. This is the time-period of revolution of this comet.

When intensity of incident photons increases, the number of electrons emitted from the surface increases due to which current increases. Frequency of incident photons only limits the maximum kinetic energy of the photoelectron emitted and so the current is independent of frequency of photon.

Initial momentum of the ball,
P_i​ = 0
Final momentum of the ball,
P_f  = mv
⇒ 0.25×10 = 2.5 kg m/s
Impulse imparted on the ball,
I = P_f − P_i 
⇒ I = 2.5 − 0 = 2.5 N s

For the last 5 years, the interest earned would be: 30% of 360 = 108. Thus, interest earned in the first 4 years would be Rs. 72 → Rs. 18 every year on an amount of Rs. 360- which means that the rate of interest is 5%

He will complete the work in 20 days. Hence, he will complete ten times the work in 200 days.

384 – 32 / 714 ÷ 102 = 50.285

So Option C is correct

312 ÷ 8 = 39

So Option E is correct

LCM (6, 8, 15, 30) – 4 = 120 – 4 = 116

Answer – d) 46kg Explanation : Suppose initially price per kg of rice is 100 then their expenditure is 5000.
Now their expenditure is only increased by only 20% i.e – 6000.
Increased price of rice = 130.
So new consumption = 6000/130 = 46

Answer – b) 5280 Explanation : 4000 + 800 + 480 = 5280

Sound is produced by larynx or voice box.

The age of 3^rd son = 1/3 × 60 = 20 yrs
Age of 1^st son = 20 + 8 = 28 yrs
Age of 2^nd son = 28 - 4 = 24 years
Ratio of their ages = 28 : 24 : 20 = 7 : 6 : 5
As per question, 7x + 6x + 5x = 12,00,000, i.e., 18x = 12,00,000
So, x = 66,666.66
Share of 2nd son = 6x = 6 × 66,666.66 = Rs. 4,00,000

It is known that expenditure of Brian is 2^rd/3 of his income.
Let Brian`s monthly income be $36.
Then, his expenditure will be $24.
Total savings of Brian = $12
Ratio of savings of Brian to that of Sam is given as 2 : 3.
Hence, savings of Sam = $18
Now, ratio of incomes = Brian : Sam = 3 : 4
As Brian`s income = $36, then income of Sam will be $48.
So, ratio of expenditure of Brian to that of Sam = 24 : 30 or 4 : 5

Let the total number of pens bought be x.
Total CP = Rs. 540

On simplifying, we get
6x2 - 66x - 1080 = 0
(x - 20)(x + 9) = 0
 x = 20 or x = -9
Therefore, 20 pens were bought.

Volume of water in the reservoir = Area of cross-section of pipe × Empty rate × Empty time
Let the empty time be t.

The resulting cuboid has dimensions:
ℓ = (6 + 6) cm = 12 cm
b = 6 cm
h = 6 cm
Therefore, surface area of the cuboid
= 2(ℓb + bh + hℓ)
= 2[12 × 6 + 6 × 6 + 6 × 12] cm² = 360 cm² 

When an object is heated, its particles gain energy and move more vigorously, causing an increase in volume.

National Highway 4 or NH4 is a National Highway in Northern India that links the national capital New Delhi to the town of Attari in Punjab near the India-Pakistan border.
