## Complete the series: 2, 4, 3, 9, 4, 16 ,5 ,25, 6,……?

A) 30

B) 33

C) 36

D) 40

There are two series: i) 2, 3, 4, 5, ……

ii) 4, 9, 16, 25, …..

In series (ii) :       4 + 5 = 9

9 + 7 = 16

16 + 9 = 25

25 + 11 = 36

## If the cost price is 25% of the selling price. Then what is the profit percent?

A) 150%

B) 200%

C) 300%

D) 350%

Let the S.P = 100
then C.P = 25

Profit = 75

Profit% = 75/25 * 100 = 300%

## A toy is sold for Rs. 220, what was the cost if the rate of profit was 10% of the cost?

A) Rs.196

B) Rs.198

C) Rs.200

D) Rs.210

Given Data

S.P = 220     Gain=10%  C.P=?

We know that :

S.P=[ 100 +Gain]/100 * C.P

We Have to find C.P, so re-arrange formula

⇒ C.P= 100/[ 100 +Gain] * S.P

Putting given data:

⇒ C.P= 100/[ 100 +10] * 220

⇒ C.P=200

## 6, 9, 18, 45, 126, ….?

A) 369

B) 359

C) 329

D) 317

Multiply given number by 3,  After multiply subtract 9 from same number:

6*3=18-9=9

9*3=27-9=18

18*3=54-9=45

45*3=135-9=126

126*3=378-9=369

## Complete the series:

6, 9, 13, 16, 20, 23, ……..

A) 26, 30

B) 26, 31

C) 27, 30

D) 27, 31

First add 3 the 4 in whole series:

6+3=9     ,      9+4=13

13+3=16 ,     16+4=20

20+3=23  ,     23+4=27

27+3=30

## A man bought some toys at the Rs. 60 and sold them Rs.50. Find his loss percent?

A) 10%

B) 16.6%

C) 25.8%

D) 30%

As S.P<C.P , so we get loss

Loss  = C.P-S.P

=60-50

= 10

Now,

Loss%= [ 100*Loss]/C.P

=[ 100*10]/60

=16.6%

## Find the missing numbers in the following series:

60, 59, 57, 54, 50, ……

A) 45

B) 47

C) 44

D) 43

60-1=59

59-2=57

57-3=54

54-4=50

50-5=45

## Find the missing numbers in the following number series:

3, 3, 5, 5, 7, 7, ……..

A) 8, 8

B) 10, 10

C) 9, 9

D) None of these

## An article is purchased for Rs. 450 and sold for Rs. 495. Find the gain percent?

A) 10%

B) 20%

C) 25%

D) 30%

Given that: C.P=450 & S.P=495

When S.P is greater than C.P, we get Profit

Profit=S.P-C.P

Profit=495-450

Profit = 45

Now ,

Gain% = [100*Gain]/C.P

= [100*45]/450

= 10%

## Insert the missing number 6 8 10 11 14 15 ……

A) 12

B) 16

C) 14

D) 18

There are two series

First                                  Second

6+4=10                            8+3=11

10+4=14                        11+4=15

14+4=18                        15+5=20
