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

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

7 unit in 2 days

105 unit in 30 days

108 unit in 31 days

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..
