Question :

Find the number of ways of arranging the letters in the word BEACHFRONT if the second and third letters must be vowels and the last letter must be a consonant. Please explain

Answer : 

Explanation of above question is provided below:
Last letter must be consonant and there are 7 consonants. So number of ways to fill last letter = 7P1. 
Second and third letter must be vowels and there are 3 vowels. So number of ways to fill second and third letters = 3P2.
Now 7 positions are remaining and there are 7 letters remaining. So number of ways for remaining 7 letters = 7P7
Total number of ways is multiplication of above 3 cases. Calculation is shown below. 


So total number of ways = 211680

If you have any queries regarding above solution please comment below.

Superposition Theorem Requirement: Power System is a complex network having number of voltage and current sources and number of loads. Now to analyze the network we need to find voltage/current at particular branch or load.  In such cases calculations for thevenin's and norton's theorem becomes difficult. We can use superposition theorem to find voltage/current at any branch or load in complex network. In this theorem only one source considered at a time and total voltage/current is sum of voltage/current obtained by considering individual source.   Statement of Superposition Theorem:

  Question : When a reverse bias is applied to a germanium PN junction diode, the reverse saturation current at room temperature is 0.3m A. Determine the current flowing in the diode when 0.15v forward bias is applied at room temperature. Solution : Given Io = 0.3 * 10-6A and VF = 0.15v The current flowing through the PN diode under forward bias is I = Io (e^(40VF) -1) for germanium diode = 0.3 * 10^(-6) (e^(40*0.15) -1) = 120.73mA.
