Here you can see that water is 40% it means 240 gm of water and 360 gms of salt
ReplyDeletewe have to remove the water and salt will always remain 360 gms.
Therefore, after evaporation salt will become 75 % of total
now 360 = 3/4 of total
total = 480
now water will be 120 gms
and initially water was 240 gms so we have to evaporate 120 gms of water
Thank you sir.
ReplyDeletemohit after spending 28% of his monthly salary in buying electronic goods and 22% monthly salary in repair work of furniture,invested 40% of the remaining in fixed deposits.if he left with 16,350/-how much is his monthly salary?sir answer is 54,500/-
ReplyDeletebut I didn't get it
I did like this
total expenditure is 90% so remaining 10%=16,350/- so 100% is 1,63,500/- but is wrong sir. Then how to solve it sir.
Total exp is 50% and 40% of remaining 50% = 2/5 x 1/2 x = 1/5x
ReplyDeleteNow he has spend 1/2 + 1/5 = 7/10 and left with 3/10x = 16350 = 54500
sir it mean that we need to take 28+22=50 and then remaining is 50 in that 40% isn't it?
Deletesir it mean that we need to take 28+22=50 and then remaining is 50 in that 40% isn't it?
Deletesir please explain it once again I didn't get it please...
DeleteAbsolutely correct
ReplyDeleteNow he has spend 1/2 + 1/5 = 7/10 I didn't understand this one sir
Delete1/2 he has already spent and 40 % of remaining 50% in the form of investment which is 1/5 and total exp is 1/2 +1/5 = 7/10
ReplyDeleteFor example u have 100 rs u spent 50 on petrol and out of remaining 50 u spnt 40% whichs comes to 20 and total consp is 70 which is 7/10
I got it sir thank you sir.
ReplyDeletesir please ans it is it possible without equations .the total population of the village is 8800. in the beginning of the year 2001. in the particular year number of males and females in the village is increased by 12% and 15%.hence at the beginning of the 2002 the population of the village is 10024.what is the total male population in the beginning year 2001? ans is 3200
ReplyDeleteI tried it as m+f =8800
112%m+115%f=10024
sir please answer this 6 people u v w x y z carry bags of different weights.w carries a bag heavier than only 2 people.u carries a bag lighter than v and z.the bag carried by u is heavier than that of w.z doesn't carry heaviest bag and x doesn't carry lightest bag.the second heaviest bag weights 21kg. the second lightest bag weights 11kg.
ReplyDeletequestions is who among the carry third heaviest bag?ans is u
sir explain this too .a long straight line 1482m long.58 trees are planted at equal distances one tree being at each end of the line.what is the distance between two consecutive trees.ans is 26
ReplyDeleteMale female ques be soved with options
ReplyDeleteChk option randomly one by one u ll get ans within one min.
For exp if u see increase in the pop is 1224.
So take optipn 3200 as male
Now female ll be 5600
12 % of 3200 is 320+64
15% of 5600 is 560 + 280
Now add all of them
Ans is 1224 so ans is 3200
U need to b really fast wd nos.
Now look at the puzzle step by step
ReplyDeleteThere are six people wherein W is heavier than only two people
So W is at the 4th no.
Equ will b _,_,_,W,_,_
We will arrange equ in descending order
Heaviest to lightest
Now U carries the bag lighter than V n Z
U will always b placed behind V n Z
Something like that VZU or ZVU
Now U is heavier than W
So U will b at first three places as W is fourth and as V and Z are heavier than U so U must come at third place and V n Z should be first and second or second and first
As Z does not carry heaviest bag so V shold be fist and Z should be second
Now d equ is V,Z,U,W,_,_
As X is not the lightest so it ll be 5th and Now Y is left for only last place vacant
So the equ will be
V Z U W X Y
and ans is U
Let me kn if u want any clarification
you are super sir.no words to say
DeleteNow tree ques
ReplyDeleteIf you will carefully imagine 58 trees will make 57 divisions of 1482 mts . So divide 1482 by 57. You ll get d ans
For ex if u ll plant 2 trees there is one single line of 26 mts and if u plant three trees therell be 2 divisions of 26 mts and 52 mts total line. likewise 58 trees 57 divisions and 1482 mts line
Got it or not
yes I understood sir.
Deletethank you so much sir.
ReplyDeletesir please answer this a trader fixes the marked price of his goods such that he makes profit 14.8% by selling an article after giving an 18% discount. however one customer availed 45% discount instead of 18% percent.what is the % loss incurred by the trader in the case of his particular customer? ans is 23
ReplyDeleteLet MP be 100
Deleteso after discount SP be 82
now 82 = 114.8 % of CP
CP = 71 approx.
and after discount of 45%. SP will be 55
now loss is 71-55 = 16
Loss % = 16/71 = 23%
thank you sir
Deletesir one more question puneeth started working on a fresh project independently.after finishing 30% of the work he left.vikas took over and could finish in remaining 28 days.independently.if puneeth is 20%less efficient than vikas for how many days did puneeth work on the project?ans 15
ReplyDeletepuneeth did 30% work means 3/10 work and 7/10 completed by vikas in 28 days.
DeleteIt means vikas will take 40 days to complete the work alone.
now puneeth is 20% less efficient means he will take 20% more time than vikas which is 48 days,
now he did 3/10 work so ans is 48 x 3/10 which is 14.4 days aprrox 15 days ans
Thank you sir.
Deletehow did u get work done by vikas was 40 days
DeleteA certain sum was invested in scheme A for a certain number of years. Scheme A offers simple interest

ReplyDeletePuneet started working on a fresh project independently. After finishing 30% of the work he left Then
ReplyDeleteVikas took over and could finish the remaining work in 28 days independently. If Puneet is 20% less efficient
than Vikas, for how many days did he (Puneet) work on the project?
Puberty 30% vikas 70% so ratio 3:7 7 parts 28 then 10 parts 40 puberty 20% less efficient means 40*100/80= 50 puneet completed 30% so 50*30/100= 15days
