A tap fills the tank with water in 2 hours. But due to the leakage of water due to a leakage in the tank, the tank fills in \(2 \frac{1}{3}\) hours. In how many hours will the leakage empty the tank?
Match Old name with the new name. Old Name  New Name I. Allahabad Junction a) Pandit Deen Dayal Upadhyaya Junction II. Manduadih railway station b) Prayagraj Junction III. Mughalsarai junction c) Prayagraj Rambaug Railway station IV. Allahabad City railway station d) Banaras Railway Station Choose the correct code given below:
Assertion (A): A p-n junction diode with low junction depth can be used as a solar cell when illuminated by suitable light (wavelength) at the top thin layer above the junction. Reason (R): A p-n junction diode under no condition can be used as a solar cell. It can be used only as a light-emitting diode for optoelectronic applications.
Sourab hires a car at junction A and drives 16 km towards north. He takes a right turn and drives 30 km to reach a bus stand. He now drives 10 km after taking a left turn to reach a petrol bunk. Finally, he takes a left turn and drives 30 km, and stops at Junction B. How far is junction A with respect to junction B?

There are 2 taps connected to a bucket. One tap flow hot water and other tap flow cold water. Hot water tap can fill the bucket in 15 min and cold water tap can fill the bucket in 10 min. A person opened both the tap and left the place. He returned at the time when bucket should be full but he found that due to leakage in the bottom of bucket. It is yet to be full. He reported the leakage and bucket become full in 2 minutes more, in how much time leakage can empty the bucket alone?
Due to leak in the bottom of the tank, it require 45 min more to fill the tank completely as compared to no leakage situation. Without leakage, tank require 3 hours to fill the tank. How much time it takes to empty the tank through leakage?
Given below are two quantities named A and B. Based on the given information, you have to determine the relation between the two quantities. You should use the given data and your knowledge of Mathematics to choose between the possible answers. Two taps A and B can fill a tank in 12 hrs and 18 hrs respectively. Both taps are opened together but it was found that it took 108 minutes more to fill the tank due to leakage C at the bottom of the tank. Quantity A: If the tank is full, find the time in which the leakage would empty it. Quantity B: If the tap A works half its efficiency, tap B works 3/4th of its efficiency and leakage C drains double amount of water than earlier, then in what time an empty tank will get full?
