Explanation of word problem plz
1=3
2=29-3/7
4=70
5=2/15
is it correct?
Word problems kse solve hogi
Ansr of 2nd word problem 31 days?
yes
yes
36…27
108
3..4
7 in 2 days
7*15=105-108=3/3 by a
15*2+1=31
27 how?
1/3 w =12 => 1 work =36 day by A
now A:B =3:4 = eff.ratio
=> A:B=4:3 = tym ratio
now 4 ratio =36 => 3 ratio =27 =b
=> a =36
=> b =27
lcm =108 so a =3 and b =4
a——-b——-a——-b
3——-4——-3——4
=> 7 work =2 days
=> 105 work =30 days
remaining work =108 -105 =3
=> 3A =3 => a =1 day
so total days =30+1 =31 days

okk
yes..in 1 ans will be 6…
need DI question
Let total ruppes Rakesh have 100x
In PPF he invested = 12x
In clothes he invested = 3/8* 88 = 33x
33 X – 12x = 10500
21x = 10500
X = 500
Total amount = 50000
House + other = 27500
House = other – 1500
O – 1500 + O = 27500
2O = 29000
O = 14500
H = 13000
Bag A Bag B
Red – 5 Red – 5
Green – 8. Green – 4
Yellow -7 yellow -6
5C2/ 15C2 = 2/21
green ball in bag A 8 kaise aaaya …plz tell

108
B -27. 4
7 unit in 2 days
105 unit in 30 days
108 unit in 31 days
pls say how you got 27
3) let salary be x
ppf=12x/100
remain=>88x/100
clothes=33x/100
remain=>55x/100
a/c
33x/100 — 12x/100 = 10500
x=50000
other – household =1500
other = 1500 +household
a/c
other + household =27500
2h=26000
h=13000
a b c
600*12 500*4 5x*8
x*24000/230+x 5600
x=70
70 how
40x=5600
x=140
i think its 70%
how please solve
140 he aayega
thanks sir..
Bro ,could u plz explain 1 first one??
24k ki jagh 18400 hona chaiye na
2) 31
5) 2/21
A : B : C
C = 500*X/100 = 5X
600*12 : 500*4 : 5X *8
180 : 50 : X
X / 230+X = 5600/24000
X / 230+X = 7/30
30 X = 230*7 + 7X
23 X = 230*7
X = 70
thanks
24000 ki jgh 18400 hona chaiye na
Q1 – ANS 8 when it takes T=19 sec with boxes
2)
A=36
B=27
LCM 108
A…3
B…4
108/7=15*3/7
15 pair mean 15*2=30
Rest work 3/3=1days
30+1=31
3)consider rakesh salary 100
Ppf=12
Rest 88*3/8=33 spend for purchasing clothes
Diff…33-12=21…..10500
Total amt 50000
Now,
55/100*50000=27500
X+x-5000=27500
X=14000
&13500
4)
1800:500:5x
5x/(2300+5x)=7/30
X=70
I think 1st some value are wrong because platform dist less than train..
5)
5c2/15c2=2/21 simple one..
