well i find direct placing of these volumes according to ratio easy but this it didnot work thanx @krum for this new method

@soumitrabengeri said:Here is oneThree diggers dug a ditch 324 m deep in 6 days working simultaneously. During one shift, the third digger digs as many more meters more than the second as the second digs more than the first. The third digger's work in 10 days is equal to the first digger's work in 14 days.How many meters does the first digger dig per shift?1) 15m2) 18m3) 21m4) 27m
let first person dig k metres in one day
second digger=k+x
third digger=k+2x
324=6*(3k+3x)
k+x=18
10(k+2x)=14k
k=5x
6x=18
x=3
k=15

clearly 0 is out of picture for obvious reasons
5,7 are also out as no other number from 0-9 can match their factors
among those left, 3 and 6 pair up for 9; 2 and 4 pair up for 8

@gs4890 said:plz explain in thoda detail b
Three persons' one day's work : 54
z-y = y-x -----> y=(z+x)/2 ....... (1)
also , z= 1.4x ......(2)
and x+y+z= 54........(3)
x=15.
@soumitrabengeri said:3 vessels having volume in the ratio 1:2:3 are full of mixture of coke(coca-cola waala ) and soda. In the first vessel, ratio of coke and soda is 2:3, in the second 3:7 and in the third 1:4If the liquid in all 3 vessels were mixed in a bigger container, what is resulting mixture of coke and soda?1) 4:112) 5:73) 7:114) 7:5Please post the method as well so that everyone understands now and for future reference as well..a humble request
let the volume of the first vessel be 20
second vessel=40
third vessel=60
1st vessel 2nd vessel 3rd vessel
coke:: 8 12 12 =32
soda:: 12 28 48 =88
32/88=4/11

@sauravd2001 said:@chandrakant.k aa gaya bhai samjh
ha aa gaya thanks 😃 😃
P.Q.R = X.Y.Z = Q.A.Y
These can take any values from 0...9
now no value can take 0 since the product has to be 0 which is not possiblle..
Now 5 and 7 since are prime, any multiple of this will not be possible
So 0 5 7 are the number which are not in the list so sum = 12
So for 2nd question NOT
So 1 2 3 4 6 8 9 are the 7 digits
P*Q*R*X*Y*Z*Q*A*Y = 1*2*3*4*6*8*9*Q*Y = 2^7*3^4 = K^3
From this we understand that we need 2^9 and 3^6
So Q and Y = 4 and 9 no matter which order
SO K = 72 so A = 2

@krum ohk brother yeah m too lazy for all this but u told so sure yeah i will keep this thing in mind boss
In how many ways u can write 19 as a sum of 5 odd numbers?
@bullseyes said:In how many ways u can write 19 as a sum of 5 odd numbers?
NONE if numbers cannot be same.. Please tell if they can be same
EDITED : Infinite???
Since we can use neagtive numbers as well???
