As per the Question:
= 2/7 of Adam= 1/5 of Ben
Therefore Adam's amount= 1/14 * 7/2=1/4 Ben
= Adam/Ben=1/4 of 1:4
Thus Ben's share= 2420*4/5= 1936
Hence Option B is the correct one.

Let us presume the 3’rd number as n

Then the 1’st number P= 125% of n or +\frac{125n}{100}=\frac{5}{4} n

2’nd number Q=\frac{160n}{100} \frac{8}{5}n

Hence the ratio between P and Q=\frac{5n}{4} : \frac{8n}{5}

= 25n: 32n or 25: 32

Therefore option A is the correct one.

Let the shares of L, M, N, O be Rs. 4n, Rs.n, 6n, and Rs.3n respectively.

Then, 6n – 3n = 1500

Hence n = 500

Therefore M's share = Rs. n = Rs. (1 x 500) = Rs. 500.

Thus option D is the correct one.

Let’s presume the number of seats for Men, women and Older adults as  6n, 9n, and 5n respectively.

Now ratio after increasing the membership seats= (120% of 6n), (180% of 9n), and (120% of 5n).

\frac{120n}{100} * 6n ; \frac{180n}{100} * 2n ; \frac{120n}{100} *5n

\frac{24n}{5} ; \frac{18n}{5}; 6n

= 24n: 18n: 30n

= 4: 3: 5

Therefore option B is the correct one

Let both the number be x and y

Given, 50% of x = 1/3 of y

Then, 50/100x = 1/3y

1/2x = 1/3y

x/y = 1/3 * 2/1 = 2/3

Therefore, x : y = 2 : 3

Correct answer A

Let’s presume the numbers as p and q

2/3p= 1/6q

Therefore p= 1/6*3/2= 1/4q

Now it is mentioned that

2/7(p)= 5/8(q)

By putting the value of p in the equation, we get:

2/7*1/4q= 5/8*q

2/28q= 5/8q

1/7q= 5/2q

Therefore the ration will be 4:35 (2*2): (7*5)

Hence option C is the correct one.

Wheat flour to white flour ratio= 2:3

Total ratio= 5

Wheat flour to white flour = 2/5*100= 40

Hence option B is the correct one.

Profit percentage= Profit/Cost Price*100

Profit= SP – CP= m²-n²

CP = n²

Therefore profit % = (m²-n²)*100/ n²

Hence Option B is the correct one.

The total volume of the soap and water mixture given is 44 liters.

Given, the ratio of water to soap = 7:4

Total of ratio = 7 + 4 = 11

The fraction of water = 7/11

The fraction of soap = 4/11

Amount of water = 7/11 *44 = 7 x 4 = 28 liters

Amount of soap = 4/11 * 44 = 4 x 4 = 16 liters

When you take out 4 liters of the mixture and replace it with water than the new ratio:

44 liters - 4 liters  = 40 liters

Then the new volume of water

7/11 x 40 = 25.45

The quantity of water in the mixture will be:

25.45 liters + 4 liters = 29.45 liters

The quantity of soap in the mixture will be

44 - 29.45 = 14.55

Therefore, the ratio of water and soap is 29.45: 14.55

Correct answer C

Let the quantity of juice in the mixture be X

Cost per litre = 90 Paisa

So we have (X+16)*90= X*108+16*0 (Sice the cost of water is nil)

90X+16*90= 108X

18X= 16*90 therefore X= 16*90/18= 80

Therefore option C is the correct one.

Milk to water ratio= 2:3

Total ratio= 5

Milk to water= 2/5*100= 40

Hence option B is the correct one.

The total volume of the soap and water mixture given is 44 liters.

Given, ratio of water to soap = 7:4

Total of ratio = 7 + 4 = 11

Fraction of water = 7/11

Fraction of soap = 4/11

Amount of water = 7/11 *44 = 7 x 4 = 28 liters

Amount of soap = 4/11 * 44 = 4 x 4 = 16 liters

When you take out 4 liters of the mixture and replace it with water then the new ratio:

44 liters - 4 liters = 40 liters

Then the new volume of water

7/11 x 40 = 25.45

The quantity of water in the mixture will be:

25.45 liters + 4 liters = 29.45 liters

The quantity of soap in the mixture will be:

4/11*40 = 14.5

14.5 + 4 = 18.5 liters

Hence Option D is the correct one

Let the number of men and women be 7x and 8x

Then the increased number will be 120/100 * 7x and 110/100 * 8x

= 42x/5 : 44x/5 = 21 : 22

Hence Option D is the correct one.

(1.2 * 9) = (y * 4)

10.8 = 4y

y = 2.7

Hence Option B is the correct one.

Let the initial number of men and women in the office be 5n and 6n respectively

After increasing their %  new ratio= 120% of 5n) and (130% of 6n).

\frac{120}{100}* 5n; \frac{130}{100}*6n

= 6n: \frac{39n}{5} or 30:39 or 10: 13

Hence option B is the correct one.

 

\frac{125n}{100}

Therefore n= 2.03

Hence Option A is the correct one.

Explanation:

Let the 3 numbers be p, q, and r

Then p: q= 3: 4 and q: r= 7: 8

= 7* : 8* = 4:

P: q: r= 3: 4:  = 21: 28: 32

Therefore q= 162* \frac{28}{81}= 56

Hence Option B is the correct one.

Ratio mentioned in the question= \frac{1}{3}:\frac{2}{3}:\frac{1}{8}  or 8:16:3

Therefore Ben will get= 1539* \frac{8}{27} = 456

Hence Option A is the correct one.

Let their wages be = 4w, 5w, and w

After increment new wages:

L=\frac{110}{100}*4w= \frac{22w}{5} M=   \frac{120}{100}*5w= 6w and N=\frac{120}{100}*w \frac{6w}{5}

Therefore the new ratio of their salary= \frac{22w}{5}:6w \frac{6w}{5} = or 11: 15: 3

Hence Option C is the correct one.

Given, 5: 8:: p: 16

Then, 5/8 :: p/16

= 5*16 = 8p

8p = 80

Therefore, p= 10

Hence Option A is the correct one.

Let L’s salary be 2000

M’s salary be 4000

N’s salary be 5000

New salary of L = 4000

New salary of M = 6500

New salary of N = 8000

Therefore, the new ratio of their salaries will be 40: 65: 80 = 8: 13: 16

Hence Option C is the correct one.

Let both the numbers be 3n and 5n

Given, 3n – 12 = 6

Given, 5n – 12 = 15

Then,3n-12 /5n-12 =6/15

15(3n – 12) = 6(5n – 12)

45n – 180 = 30n – 72

5n= 108 therefore n= 21.6

Therefore, the greater number will be 3*21.6 = 64.8

Hence Option B is the correct one.

Given 20% of p=1/3 of q

Then 20/100p = 1q/3

=p/5 = q/3

=  or p: q= 5:3

Hence option B is the correct one.

Let the 1’st proportional be p

Then p: 3: 16: 8

8p= 48 therefore p= 48/8 = 6

Hence Option B is the correct one.

Let the numbers be 4n and 5n

Then 4n-11/5n-11 = 11/24

= 24(4n-11)= 11(5n-11)

= 96n- 264= 55n- 121

41n= 143

Therefore n= 3.48 Hence the bigger number will be 5*3.48= 17.43

Hence option A is the correct one.

Let the number of 50, 25 and 10 paise coins be 5n, 4n, and n, respectively.

Total of their values=5n * 50/100 +4n * 25/100+ 2n * 10/100 = 36n/10 = 36n/10 = 36n/10 =180   = 36n= 1800 therefore n= 1800/36 =50

Hence then number of 10 paise coins= 2*50= 100

Therefore option A is the correct one.

Amount of Urea in the 1st version = 0.50 × 400 = 200 g.
Amount of Urea in the 2nd version = 0.80 × 600 = 480 g.
Total amount of Urea = 200+480 = 680 g.

Therefore the percentage of concentration = 680/400+600 * 100 =68%

Hence Option A is the correct one.

As per the question 2P= 3Q= 5R and also P+Q+R= Rs 780

Therefore P + 2p/ 3 + 2p/5 =775

= 31P= 775*15= 11625= 31P or P=11625/31 =375

Hence option A is the correct one.

Let both the numbers be 6x and 13x

Given, 6x – 14 = 16

Given, 13x – 14 = 25

Then, 6x-14 / 13x-14 = 16/25

25(6x-14)= 16(13x-14)

150x- 350= 208x- 224

= 126= 58x therefore x= 2.17

Hence the smallest number will be 2.17*6= 13.03

Thus option B is the correct one
