[@sanketpatil279]

Answer to question 4 is wrong i think. I feel Answer is 1440, Since no Two vowels are together, vowels can only be placed in this way. V_V_V_V_V Since there are 5 vowels, and 9 letters, any other formation will violate the rule. In the 4 blanks the remaining consonants will go. I repeated twice, hence divided by 2. 5*4*4*3*3*2*2*1*1 / 2 2880/2 = 1440

Q.2 Ans 4 digit numbers= 7!/(7-4)! = 7!/3! = 840 Total 4-digit numbers are 840 which includes also those numbers having 0 as most left digit like 0134, 0479 etc which can be written as 132 and 479 which are not 4 digit numbers. Therefore we will first calculate total number of 4 digit numbers which have 0 as most left digit.when fixing 0 as most left digit then there leftovers only 6 digits which can swap there places and we now need to take only 3 digits at a time, we therefore do calculations as follows; Number of 4 digital numbers having 0 as most left digit= 6!/(6-3)! = 6!/3! = 120 Valuable 4 -digit numbers= 840-120=720

Bhai mere jab last me place hi ek h to tum 5 thing ko kaise arrange karoge 5p1 karoge jiska value 5 hi hota h. In brefiely- 9*10*10*10*(1)=9000 9*10*10*10*(3)=9000 9*10*10*10*(5)=9000 9*10*10*10*(7)=9000 9*10*10*10*(9)=9000 =45000
