About Black Hole

• A black hole is an extremely dense object whose gravity is so strong that nothing, not even light, can escape it.
• A black hole does not have a surface, like a planet or star. Instead, it is a region of space where matter has collapsed in on itself.
• This catastrophic collapse results in a huge amount of mass being concentrated in an incredibly small area.

About Event Horizon Telescope (EHT)

• The EHT is not a single telescope but a worldwide network of radio telescopes that work together to study a common object in space.
• Very-long baseline interferometry: It is the technique, where the data each telescope collects about the object is correlated with data from the others using extremely precise clocks.
• In this setup, the maximum distance between the telescopes defines the network’s resolution.
• The Greenland Telescope has been commissioned to the array, which has improved the resolution of the EHT in the north-south direction.

The Event Horizon Telescope (EHT) Collaboration has released new images of M87, the supermassive black hole at the center of the galaxy Messier 87.

A tap can fill a tank in 4 hours.
Therefore the tap can fill half the tank in 2 hours.
Remaining part = 1/2
After half the tank is filled, two more similar taps are opened.
Hence, total number of taps becomes 3.
Part filled by one tap in 1 hour = 1/4
Part filled by three taps in 1 hour 
= 3 × 1/4 = 3/4
i.e., 4 taps can fill remaining half in 40 minutes.
Total time taken = 2 hour + 40 minute 
= 2 hour 40 minutes

part filled in 2 hours = 
Remaining  part =  
∴ (A + B)'s 7 hour's work = 2/3
(A + B)'s 1 hour's work = 2/21
∴ C's 1 hour's work = {(A + B + C)'s 1 hour's  work} - {(A + B)'s 1 hour's work}

∴ C alone can fill the tank in 14 hours.

Gain = 10%
Let the C.P. be x.

Let the original price be Rs. 100.
Marked down price = Rs. 80
Now, we want to raise 80 to 100.

Simple Interest = PRT / 100
Here P = Principal, R = Rate of interest and T = time period
Hence, Simple Interest ∝ T
Required Ratio = (Simple Interest for 5 years) / (Simple Interest for 15 years)
⇒ T₁/ T₂ = 5 / 15
⇒ 1 / 3 = 1 : 3
