__11-20__**Simplifications:**

- (20/4 × ? ) 40% = 48
- (2.5+1.5) (3.5+1.5)= ?
- ?÷60 -3 /4 = 3 1/3
- ?% of (152÷19×45) = 126
- 46% of 600+ 44% of 225=?
- 12×9 ÷ ?×15 = 16+38
- ? ÷ 12×4/0.6=250
- ?+0.4= (1.6+5.4)÷2.5

Sum of 4 consecutive even numbers is 81 more than the sum of 3 consecutive odd numbers, sum of least even and odd number is 59.find the difference between large even and large odd numbers?

plz any one explaining this

conc.even no =2a,2a+2,2a+4,2a+6 =8a+12

conc odd no =2b+1,2b+3,+2b+5 =6b+9

now frm 1st cond

8a+12 =81+6b+9

=>8a-6b =78——————–(1)

frm 2nd cond

2a+2b+1 =59

=>a+b =29———————–(2)

from here a =18 and b =11

even no,36,38,40 ,42

odd no =23,25,27

so E(L)-O(L) =42-27 =15..

@Shubhra_AspirantsZone:disqus maam eng ques plzz post

@mod

please explain question 7

1 ratio =3

so downstream =x+y =27

now y =3 so x =24

so upstream =x-y =24-3 =21

so distance =21*5 =105kms

thanks bhai

A can do a work in 24. B is 20% more efficient than A. C take 10 more days than B alone to finish the same work. How long A & C will take to do the same work?

A:B =5:6——-EFF RATIO

=>6:5 TIME RATIO

NOW 6 RATIO =24=A

SO 5 RATIO =20 =B

NOW C =30 DAYS

A===24

C===30

LCM 120

SO A =5 AND C =4

SO 9(A+C) =120

SO A+C =120/9 =40/3 =13(1/3) DAYS

thanks, when ur exam is..?

ON 9TH

The ratio of Milk to water is 5:4, if two litres of water is added, ratio becomes 10:9, then find new amount of water in the mixture.

solve this bro my answer

45x=40x+20

5x=20

x=4

water value 4*4+2=18 ans check answer is correct

4/9———————1

———–9/19——–

10/19——————5/171

RATIO =18:1

NOW 1 RATIO =2

SO 18 RATIO =36=ORIGINAL SOLN

NOW WATER =4/9*36 =16LTRS

SO NEW AMT WILL B 16+2 =18LTRS

EDITED SOLN H BRO PHLE REFRESH KR LENA AND URS ALSO RYT..:)

y=3 kyu?

MAM DIA HUA H NAA STREAM KI VALUE 3 H AND RATIO OF DOWNSTEAM TO STREAM KI 9:1 SO 1 =3 HAI ISLY 9 =27 HOGA..:)

ok bahot cnfusn hota h is topic me upstream downstream, if possible ap in short smjha skte ho?

yeh wala question???

no concept.. apka ho gya xam?

9TH KO H MAM..:)

MAM ISK LIYE AAPKO THODA LOGICALLY SOCHNAA PADEGA

X == MAN LIJIYE BOAT KI SPEED

Y === MAN LIJIYE RIVER KI SPEED

UPSTEAM HOTA H WORK DONE AGAINST ANY QUANTITY

AND BOAT KO AAGE BDNE K LIYE HMSHA USKI SPD RIVER KI SPD SE ZYADA HI HOGI NAA SO JB AGAINST KAAM KRENGE THEN HMSHA MINUS SIGN LGTA H

SO UPSTEAM KI SPD NIKALNI HO THN X -Y

SIMILARLY DOWNSTRAM MEANS WORK DONE WITH THAT QUANTITY SO PLUS

=>DOWNSTREAM =X+Y

YHI FUNDA H MAM.

Thank u , 1 week h apke pass to

hehehe mam doesnt matter agr papre kal bhi ho toh b mee prepared hu..agr achha jaana hoga toh kabi bhi ho achha hi jaayega and visce versa so time independent mam aapko atb mam..:)

Apko kaise pta ma’am h ? SB yha sir bolte ?

becz i saw u on affairscloud also and whaa aap mam hi ho ??

ACCHA

@mod

answer of question no 6 fraction or absolute number???????

please clarify

its 25 instead of 20

yup

thank you

sol please?

CP=====P/L=======SP

+5=====+2========+7

+5=====+0.25=====+5.25—-TAKEN 25 INSTEAD OF 20

NOW 2.25 =189

=>+5 =CP(A) =420

inta short nhi ata thoda smjha dijiye

X METHOD SE BTAU AAPKO??/

ha plzz

CP=X =>SP =7X/5 SO P(1) =2X/5

NOW CP=X AND SP =75%OF 7X/5 =21X/20

NOW P(2) =21X/20 -X =X/20

NOW P(1)+P(2) =2X/5+X/20 =9X/20

NOW 9X/20 =189 =>X =420

thanx

Two items A and B cost price equal, item A sold at 40% profit and item B sold at 20%less than the selling price of item A, total profit is 189.find the cost price of A?

idharr NOW CP=X AND SP =75%OF 7X/5 =21X/20

75 ki jagah 80 percent ni aega ?

mam actual question mn 25% less than sp of a tha and option kuch aise the 400.420 475 and 80 % se value 363 something aa rhi h naa jo options mn tha hi ni..:)

SP1=7x/5 SP2= 21x/20 after this

CP=====P/L=======SP

+5=====+2========+7

+5=====+0.25=====+5.25—-TAKEN 25 INSTEAD OF 20

NOW 2.25 =189

=>+5 =CP(A) =420

But how 0.25 comes

5.25-5 =0.25

They given 20% less than SP of A

bro i written n the left naa it took 25 instead of 20 actual question it was 25 aond options wew 400 420 475 like that…now cleared..:)

Sum of 4 consecutive even numbers is 81 more than the sum of 3 consecutive odd numbers, sum of last even and odd number is 59. Find the difference between largest even and largest odd numbers?

conc.even no =2a,2a+2,2a+4,2a+6 =8a+12

conc odd no =2b+1,2b+3,+2b+5 =6b+9

now frm 1st cond

8a+12 =81+6b+9

=>8a-6b =78——————–(1)

frm 2nd cond

2a+2b+1 =59

=>a+b =29———————–(2)

from here a =18 and b =11

even no,36,38,40 ,42

odd no =23,25,27

so E(L)-O(L) =42-27 =15..

Last even and last odd 2a 2b +1 kaise

2a+6 2b+5 ni honge??????

i think its not last its least odd and even asked in first shift thats soln is this one

1 more

Sum of 4 consecutive even numbers is 81 more than the sum of 3 consecutive odd numbers, sum of least even and odd number is 59.find the difference between large even and large odd numbers?

1 i got this 1 frm 1st shift

Thank you sir

O_O

M getting 17 as answer..

may b some mistake done mate check once again the procedure ans is 15 only ..:)

ok 🙂 thanks

my plzr mate..:)

I took

x+x+2+x+4+x+6=(4x+12) & y+y+2+y+4=(3y+6)

so 4x+12- (3y+6)=81———A

x+y=59 ————————–B

my dear mate when u r taking the odd terms means series i think it should be y+1,y+3 ,y+5 i think..:)

ok but when you put any odd no. in place of “y” in this series u’ll get an even no. na…??

thats y i use 2+ series bcz in that for any value of a x whatever it is it will give even for evn function ie 2a 2a+2—— so on and odd for odd function ie 2a+1,2a+3———-so on…:) check ur series mate 3y+6 now for 0dd it will b odd no doubt but for even???

ok 🙂 lemme try

sureee sure mate..:)

Ibps clerk 4th shift time and work questions same

A can do a work in 64 days. A is 60% more efficient than B, if A and C can do work in 21 1/3 days. find days taken by B and C together to complete the work.

Is 160/9 is the ans?

NOT SOLVED MAM I GOT THE QUESTION SO POSTED MAM..:)

Oh thanks.

A = 160% of B

A: B = 160 : 100 = 8: 5

A takes 64days ~ 8ratio.

1 ratio for 8 days,

B takes 5ratio, 8*5 = 40days.

C takes 64/3 days.

B&C together, (40*64/3) / (40 + 64/3)

40*64/ 184 = 320/23 ???????

is 24 8/21 or (512/21) ans??

Anyone knows how to crack this ?

3, 2, 3, 6, ?, 37.5

*0.5+0.5

*1+1

………..

6*2+2=14

Ohh, thank you.

Prepare Kar rahi ho, tier 2 & 3 ?

Average age of A and B, 2 years ago was 26. If age of A 5 years hence is 40 yrs, and B is 5 year younger to C, then find difference between age of A and C?

A+B=52

let A’s age 2 yrs ago be x and B’s age 2 yrs ago will be 52-x so present ages : A= (x+2) & B=(52-x+2) Given that x+2+5=40 so x=33 present ages A–35,B—21 & C—16 A-C=19

q7

x+3(dS) x-3 (Us)

x+3/3 = 9/1

x=24

Upstream = 24-3 =21

D= S*T => 21*5 = 105

The ratio of Milk to water is 5:4, if two litres of water is added, ratio becomes 10:9, then find new amount of water in the mixture. Can u tell me the solution of this question?

4/9———————1

———–9/19——–

10/19——————5/171

RATIO =18:1

NOW 1 RATIO =2

SO 18 RATIO =36=ORIGINAL SOLN

NOW WATER =4/9*36 =16LTRS

SO NEW AMT WILL B 16+2 =18LTRS

Milk : water

5x : 4x

now

5x/9

——- = 10/9

4x/9 + 2

we get x =36

4*36 = 144

new = 144+2 = 146

M:W. –>. M’:W’

5:4 –> 10:9

As water is added, so milk must not be changed. Make the ratio value of Milk same in both case.

M:W. –>. M’:W’

10:8 –> 10:9

1 rratio change for adding 2litre . water

1ratio value is 2litre.

M : W = 10 : 9= 20L : 18L

43, 58, 89, 146, ?, 378

solution?

43——–58————89———-146——–239———-378

—–15———31————57———–93———139——–

———-16———–26———-36————46—————-

————–10————-10————10———————–

so missing no.should be 239

tyyy 🙂

For Career Power, I cant tell, because I have no clear idea about it

Oliveboard sometimes give out of context questions, like very hard

I have found PraticeMock’s tests to be good. So you can take that. You will find good level of questions in this one.

Mam ap ne to ek or option add KR Diya.. 🙁

Actually career power ka I have no idea

Also, these all STs are for practice, and you cannot judge yourself based on these STs, at least for Mains exam.

Yup mam tnx for ur suggestion..wait for result and then take pm aage dekha jaega..tnx for ur time..
