 # Monotonic function

Strictly increasing function: A function f(x) is said to be a strictly increases function on (a, b) if x₁ < x₂ ⇒ f (x₁) < f (x₂) ” x₁, x₂ ϵ (a, b).Ex: aˣ is strictly increasing function on R for a > 1. F(x) = eˣ is increasing on R. Strictly decreasing function: A Read more about Monotonic function[…] Puzzle 1: A clock with the hours round the face in Roman block numbers, as illustrated in the sketch fell down and the dial broke into four parts. The numerals in each part in every case summed to a total of 20.

ELECTRODE POTENTIAL AND STANDARD ELECTRODE POTENTIALS Electrons will flow from the electrode of higher negative charge density to the electrode with lower negative electric charge density. A property closely related to the density of negative electric charge is called the electrode potential. Potential difference between the metal and metal ion in which electrode is Read more about Electrode Potential and Standard Electrode Potentials[…] # Tricky Puzzles

1. Vapour pressure of liquid-liquid solutions: Raoult’s Law:- The partial pressure of each component in a binary volatile liquid-liquid solution at a given temperature is equal to the mole fraction of that component in the solution multiplied by the vapour pressure of that component in the pure state at same temperature. PA = [nA/ (nA Read more about Vapor pressure of liquid solutions[…] # Clock Puzzles 4
