1. A man sold two articles in 12,000 each. On one he gets profit of 25% and on another he gets loss of 25%. Find his overall profit or loss percent?
A) Profit Rs1600
B) Loss Rs1600
C) Profit Rs2400
D) Loss Rs2400
E) Profit Rs2000
Option B
Solution:

.                             CP………………SP
Profit 25% =1/4     4…………………5
LOSS 25%=1/4      4…………………3
4*4 = 16 …………5*3 = 15
.                                      (-1)
15 == 24,000
1 == Rs1600 loss
2. A man wants to distribute 66rupees in a class of 60 students. He gave 1.60 rupee to each boy and 1rupee to each girl. Find how many girls were in the class?
A) 10
B) 30
C) 50
D) 40
E) 20
Option C
Solution:
6600/60=110 paisa
B……………………..G
160………………….100
.              110
10……………………….50
1………………………….5
5/6*60 =50 GIRLS
3. Two persons cover the same distance at the speed 35kmph and 40kmph respectively. Find the distance travelled if one person takes 15min more than the other?
A) 80km
B) 60km
C) 50km
D) 70km
E) 90km
Option D
Solution:
speed ratio- 35 : 40
.                     7 : 8
time ratio- 8 : 7
.                 (+1)=15
8=120min
So 35*2hr= 70km
4. A sum becomes 8000 in 2yrs and 1600 in 4yrs at compound interest. Find the sum (in Rs)?
A) 4000
B) 6000
C) 7000
D) 5600
E) 5000
Option A
Solution:
In this case when difference between time period is same then
x : y = y : z
x/8000 = 8000/16000
x= 4000
5. If a student gets 30% marks in an examination then he passes by 10 marks and if he gets 35% marks then he passes by 30 marks . find how many marks he needs to pass?
A) 100
B) 130
C) 120
D) 110
E) 150
Option D
Solution:
(+10)……..(+30)
30%………..35%
35-30 = 5%
5% = 20
1% = 4
30% = 120
Pass marks = 120-10 =110
6. Two person A & B walk from P to Q at a distance of 38km at 8kmph and 11kmph respectively. B reaches Q and returns immediately and meets A at R. find the distance from P to R?
A) 36km
B) 34km
C) 32km
D) 30km
E) 38km
Option C
Solution:
in this case both A and B cover double distance together, so time taken by them
2*38/(8+11)= 4hrs
So distance from P to R = 8*4 = 32kmph
7. A & B invest 10,000 and 11,000 respectively in a scheme. After 6months A withdrawal 20% of his investment and B add 9(1/11)% of his investment. If after one year their profit is rs8200. Find the share of B ?
A) Rs3600
B) Rs4600
C) Rs3000
D) Rs5200
E) Rs4000
Option B
Solution:
10000        11000
.          10 : 11
.          *6 *6
.          60 66……………………..(1)
A = 10000 – 2000= 8000
B = 11000+ 1000 = 12000
8000 : 12000
8 : 12
*6 *6
48 72………………………………………..(2)
60+48= 108
66+72= 138
108 : 138
18 : 23
B’s share = 23/41 *8200 =4600
8. A and B separately complete a piece of work in 25days and 40days respectively. They worked together for some time then A left the work. If B completed the remaining work in 14days, then A worked for?
A) 12days
B) 10days
C) 14days
D) 8days
E) 13days
Option B
Solution:
A = 25……..8
B = 40………5………….(LCM=200)
A+B = 13
B’s 14 days work = 5*14= 70
Means A&B together done 130 work, so together they do 13 work in a day….so 130/13=10days
9. A rectangular sheet with dimensions 22m*10m is rolled into a cylinder so that the smaller side becomes the height of the cylinder. What is the volume of the cylinder so formed ?
A) 385m²
B) 375m²
C) 365m²
D) 355m²
E) 395m²
Option A
Solution:
According to method
Volume = H *(other side)²/4∏
= 10*(22)²/(4*22/7)
= 385m²
Best approach .. see ANS will be divisible by 11. So our ANS is A
10. Find the volume of a cylinder which has height of 14m and a base of radius 3m. also find the curved surface of the cylinder?
A) 392m³,262m²
B) 396m³,264m²
C) 398m³,274m²
D) 399m³,276m²
E) 399m³,226m²
Option B
Solution:
ANS will be divisible by 11.
See …. 396..
Add alternate number and subtract the solution with middle number..
3+6=9
9 -9 =0
If the difference is 0 or multiple of 11 then it is divisible of 11.

1. \$IGi_2CoVeRT \$tRiKe\$

…:)

2. Ajit Krishna

In que no 1.
the loss pecent will be (X/10)^2 .
and if we calculate by putting X=25 , the ans will be 750.
kindly correct me i m wrong.

1. \$IGi_2CoVeRT \$tRiKe\$

cp——-p/l——sp
4——–+1———5
4———(-1)——-3
=>30 =24000—(sp)
=>32=25600–(cp)
=>loss =1600

1. \$IGi_2CoVeRT \$tRiKe\$

okk in that also same ans is coming…:)

2. \$IGi_2CoVeRT \$tRiKe\$

bhai sabi method se ek hi ans aa rha h
see here
common loss =(25)^2/100 =6.25% loss
=>6.25% =6.25/100
=>loss =6.25,cp =100 =>sp =93.75
now 93.75 =24000
=>100 =25600
=>loss =1600

1. \$IGi_2CoVeRT \$tRiKe\$

..:)

2. AMAZON

yes i too tried from that method

3. Marry..

ty ty

1. Marry..

height of cylinder, h=10
Circumference of the base of cylinder = 2πr=22
2 × (22/7) × r = 22
r=7/2
Volume of cylinder = πr2h
22/7*7/2*7/2*10====385

1. \$IGi_2CoVeRT \$tRiKe\$

yeh pi ka sign kaise bnate h???

1. Marry..

i dont know mene google se search kr copy kr diya

1. \$IGi_2CoVeRT \$tRiKe\$

okkk..thnks.:)))

2. \$IGi_2CoVeRT \$tRiKe\$

circumfence of circle se base nikal lo and volume ka formula use kr lo bro..wha se b aa jyega…;)

4. Sachin Shukla

thankuu:))

5. Misha

Mam…..Best approach .. see ANS will be divisible by 11, Explain that line in answer 9 n 10

1. \$IGi_2CoVeRT \$tRiKe\$

short trick as the ans has 22 in it so it can b divisible by 11…not applied in all cases if all options r the muliple of 11 then go by basic….:)

6. Alice

Q9/10
what’s the logic behind divisible by 11?
applicable for cylinder only?
why divisibility by 11 is being checked?
@shubra ma’am

1. Pie = 2*11 = 22
Every even number will be divided by 2. So we check by 11 of this pie to know the answer..

1. Alice

ok
thanku ma’am

7. AMAZON

Best approach .. see ANS will be divisible by 11. So our ANS is A
sir is this approach valid for all cases of cylinder?
@Suraj

1. Pie = 2*11 = 22
Every even number will be divided by 2. So we check by 11 of this pie to know the answer

1. AMAZON

@Shubhra ,Alright got this.
Mam just yesterday i asked one doubt ,i got no response from your side in Mixed Reasoning question Set 16(New Pattern), I even tagged you twice, Its my kind request to respond to it.

1. Was a little busy yesterday. Wait i will tell

1. AMAZON

I understand.
Thankyou.

8. \$IGi_2CoVeRT \$tRiKe\$

sir /mam 4 question mn jb kuch b mention nhi h….?? which typ of interst…:) but jo ans aa rha h wo ci k formule se aa rha h …jb kuch nhi mention ho to si consider kiya jta h sir/mam…:)))

1. yes simple to be taken

1. \$IGi_2CoVeRT \$tRiKe\$

but simple mn to ans hi nhi aa rha as 2 years ka amt and si dono similar aa rhe h means p=0 mam???

1. \$IGi_2CoVeRT \$tRiKe\$

if si is considerd then
8000 =p+si (2yrs)——(1)
16000 =p + si(4yrs)—-(2)
2-1
=>si (2yrs) =8000
now amt (2yrs) =8000
=>p =8000 -8000 =0
yeh aa rha mam whrn considered as si…:(

1. Yes take CI

2. \$IGi_2CoVeRT \$tRiKe\$

ok mam…;)

9. Pie = 2*11 = 22
Every even number will be divided by 2. So we check by 11 of this pie to know the answer

10. vamsy

thank you mam, explaination is awesome
