- The compound interest on (P+x) in 2 years is less by 176 on interest occurred on (P+2x) at same time. If the rate of interest is 20%, find the value of x?
- A and B invest 200 and 800 in a scheme. A withdrew his amount after 2 months and B halves his investment after 6 months. At the same time, A rejoins him with same amount. Find the profit of A from a total profit of rs 2100 if total time of investment was 1 year.

thanku az:)

no2 explain

2one also wrong:( sorry bro

1=9

3=400

bro plz explain every q in deatil plz

1 no kaise kia ho mera 8 aa raha hai…

2 no mai 360/(25*3) kar na hai na

differnce dono ka 4 h so a +b =c+d

a+b c+d se 4 extra hoga..

11+11+28=9+9+32

a+b=x+(x+28)

first answer – SHOULD BE 9

yes

how to solve 2 and 3

yes ryt..i miss read it

3=400

p+2x)*44-p+x)*44=176

44x=17600

x=400

2nd one explain please

wait

12 men can do a work in 30 days. 18 men takes as much days to complete half work as 20 women can do 1/3rd work in that time. Find in how many days 25 women can do the whole work?

total work 12*30=360

18m/1/2=20w/1/3

36m=60w

6m=10w

3m=5w

15m=25w

360/15=24

q 4 ans kya h mera 420 aa rha h

nehi 4200/11

explain plz??

a=200*2+200*6 b=800*6+400*6

so a=1600 b=7200

ratio=2:9

a=2100*2/11 =4200/11

2nd one u got it?

yaa thanks a lot

thanx to u..for correcting me:)_/_ good night bro:) tag me if any doubt.c ya

5=928 na

yes bro 🙂

last one please

7 vala ho gya ??

yes

kse ??

5000/11

detail me batao na jse phale batya tha

question me type thoda mistake he

it should be equal to ok

5000*9*4/100=(5000+x)*11*3/100

now you can find x?

okk thanku very much

refresh retyped all

1st

simple

4 extra than c

so a+b=c+d

11+11+28=9+9+32

The simple interest received on Rs 5000 at 9% per annum in 4 years to simple interest received on Rs (5000+x) at 11% per annum in 3 years. Find x

36*5000/100-5000+x)*33/100=5000/11

=========8th

In a vessel the ratio of milk and water is 4 : 1. If some quantity of water is added then ratio becomes 16 : 5. Then 21 litres of mixture is taken out and in final mixture milk becomes 64 litres. Find how much water was added to the initial mixture?

intially=4;1

later add water so ratio =16;5

change in only water so make milk equal

m;w

16;4———-intially

16;5–later

21 with draw

16x-16/5x-5

after that 64 litr milk

16x-16=64

x=5

final

80==milk

20==water

after add—intailly 16;5

16*5=80

5*4=20

so 4ltr.

q 7 me less kyu kya ??

loss bhai

interst equall bro

kaie karlo ans same he ayega

more mese less wala part deduct hoga

samj aa gya ab thanku bro

8th answer it should be 5ltr

4ltr

intailly m=w

80=20;;;;;;;;;;;;;;4;1

+5 litr

80;;25

16;5

bro solution sahi given h ..

look…ans does nt matter how i solved that matter hehehe..again eror thnku

canu pls explain3

The compound interest on (P+x) in 2 years is less by 176 on interest occurred on (P+2x) at same time. If the rate of interest is 20%, find the value of x?

p+2x)*44-p+x)*44=176

44x=17600

x=400

just using simple formula try once bro@a@aryan_chintu:disqus

Very well explained thanku and I think u 4get to xpalin question no 6

yes

hey, can u plese give the solution of Q6?

nai atta wo sorry 🙁

8 ka ans =5 aayega

initial ratio 16: 4 and after addind water

16:5 he so if X=5 then

80: 20 initial

80:25 after adding water

means water added is 5 litres

yeah bro ;;.. igave 5 write 4:)

first main 11age and 9age kaise calculate kiya…

waise direct dekh raha tha;)

but agar nikalna ho to

better to go with options
