ok ty

9/10 thankuu nice qsn pre exam type….

Three taps A,B and C can fill a tank in 12,15 and 20 hours respectively. If A is open all the time and B ,C are open for one hour each alternatively, the tank will be full in:????????

7 hr ?

how?

12…15…20 lcm 60 capacity of tank

Now a ki eff 5

B ki eff 4

C ki eff 3

Now first hr me 9 fill hoga by a n b

And next hr me 8 fill hoga by a n c

So 2 hr me 17(8+9) fill hoga

6 hr me 51 fill hoga

Left 9 a n b fill karenge next ek hr me

So finally 7 hr

kyaa dimak h aapka:))

:p

Aapse kam hi h

aree nai apka mere se bhttt jadaa h..mujhe word problem me problem hoti h…

Upar vala thodi der me karenge abhi kam h

ok

i think ur maths word problem is very strong…ab meri bhi help ho jayegi apse naa ji

Strong to nahi bas kk kk h ayega to jarur bata denge

thankuuu soo much…dear

Niche vale ka ans confirm karo

iska to 7hrs correct h…

yep

There is an empty reservoir whose capacity is 30 litres. There is an inlet pipe which fills at 5 L/min and there is an outlet pipe which empties at 4 L/min. Both the pipes function alternately for 1 minute. Assuming that the inlet pipe is the first one to function, how much time will it take for the reservoir to be filled up to its capacity???

Iska ans 60 min h ???

51min aa raha…

Yes see how

Ek inlet ek outlet h kk

First 5 l fill kar raha h

Second 4 lt out kar raha h

To acc to qus alternatively chal rahe h dono matlab firat min inlet chala second min oulet chala

To 2 min me 1 lt hi to fill hoga kuki 5 bhara 4 khali hua finally 1 hi to bhara

Ab see isme first jo given hota h na utna kam kar do matlab total 30capacity thi to 5 lt kam karo matlab 25 lt

Ab 2 min me 1 lt

To 50 min me 25 lt

Ab inlet ki bari ayegi

5 lt fill kar dega next min me

So 30 lt in 51 min

aap kis state se h?

Jaha se aap ho :p

hehehe..apko pata h mai kaha se..?

Hmm ek chat me pada tha ðŸ˜€

hehehe.. Apna uttar pradesh na uttam pradesh Yogi sarkar

isko bhi bataiye,,..na ji

Two partners investede Rs. 1250 and Rs. 850 respectively in a business. They distributed 60% of the profit equally and decide to distribute the remaining 40% as the ratio of their capitals. If one partner received Rs. 30 more than the other, find the total profit????

Let 100x profit h so 60x a n b me equally divide hoga to dono ko 30x milega

Next jo 40x h vo unke capital ke ratio me divide hoga that means

1250 : 850

25:17 now 42 =40x

So 25 =40x*25/42

And 17=40x*17/42

Iska diff lo

40x *8/42=30

So 4x= 42*3/8

100x = 42*3*25/8

=393.75

Vaise yaha ye 60 x ka koi use nahi h sidhe ratio lo and 40x me divide kar lo and phir diff lekar 30 ke equal le lo usko bas ho jayega

hum ratio tak kar liya ,,,,next kaisa solve hoga

Upar kiya to h ratio lene ke baad unka part nikalo as 40x total tha phor uska diff lo and usko 30 ke equal kar do

A:B = 25:17

40% T (25-17) /42 =30

T =393.75
