1)\u00a0Answer:\u00a0800<\/b><\/p>\n

Let the amount of money with Amal and Sunil be 6x and 4x. Now the amount of money with Mita be 5x. Difference between the largest and smallest amount is \u20b9400 i.e. 6x-4x=400 or 2x=400 or x=200 . Amount of money with Sunil is 200(4)=\u20b9800<\/p>\n

2)\u00a0Answer\u00a0(B)<\/strong><\/p>\n

Let\u00a0the salaries of Ramesh, Ganesh and Rajesh in 2010 be 6x, 5x, 7x respectively<\/p>\n

Let the salaries of Ramesh, Ganesh and Rajesh in 2015 be 3y, 4y, 3y respectively<\/p>\n

It is given that\u00a0Ramesh\u2019s salary increased by 25% during 2010-2015,3y = 1.25*6x<\/p>\n

y=2.5x<\/p>\n

Percentage increase in Rajesh’s salary = 7.5-7\/7=0.07<\/p>\n

=7%<\/p>\n

3)\u00a0Answer\u00a0(D)<\/strong><\/p>\n

Let the present age of Manisha be 5a<\/p>\n

The present age of Deepali = Xa<\/p>\n

The present age of Praneeta = 5a+9<\/p>\n

Praneeta’s age after 9 years = 5a+18=33<\/p>\n

5a=15<\/p>\n

a=3<\/p>\n

The difference between Deepali’s and Manisha’s age is the same as the present age of Parineeta<\/p>\n

Xa-5a=5a+9<\/p>\n

3X-15=15+9<\/p>\n

3X=39 ==> X=13<\/p>\n

D is the correct answer.<\/p>\n

4)\u00a0Answer\u00a0(B)<\/strong><\/p>\n

It is given that in drum 1, A and B are in the ratio 18 : 7.<\/p>\n

Let us assume that in drum 2, A and B are in the ratio x : 1.<\/p>\n

It is given that\u00a0drums 1 and 2 are mixed in the ratio 3 : 4 and in this final mixture, A and B are in the ratio 13 : 7.<\/p>\n

By equating concentration of A<\/p>\n

$\\Rightarrow$ $\\dfrac{3*\\dfrac{18}{18+7}+4*\\dfrac{x}{x+1}}{3+4} = \\dfrac{13}{13+7}$<\/p>\n

$\\Rightarrow$ $\\dfrac{54}{25}+\\dfrac{4x}{x+1} = \\dfrac{91}{20}$<\/p>\n

$\\Rightarrow$ $\\dfrac{4x}{x+1} = \\dfrac{239}{100}$<\/p>\n

$\\Rightarrow$ $x = \\dfrac{239}{161}$<\/p>\n

Therefore, we can say that in drum 2,\u00a0A and B are in the ratio $\\dfrac{239}{161}$ : 1 or 239 : 161.<\/p>\n

5)\u00a0Answer\u00a0(C)<\/strong><\/p>\n

a : b = 3:4 and b : c = 2:1 => a:b:c = 3:4:2<\/p>\n

=> a = 3x, b = 4x , c = 2x
\n=> a + b + c = 9x<\/p>\n

=> a + b + c is a multiple of 9.
\nFrom the given options only, option C is a multiple of 9<\/p>\n

6)\u00a0Answer\u00a0(C)<\/strong><\/p>\n

Initially let’s consider A and B as one component<\/p>\n

The volume of the mixture is doubled by\u00a0adding A(60% alcohol) i.e they are mixed in 1:1 ratio and the resultant mixture has 72% alcohol.<\/p>\n

Let the percentage of alcohol in component 1 be ‘x’.<\/p>\n

Using allegations ,\u00a0$\\frac{\\left(72-60\\right)}{x-72}=\\frac{1}{1}$ => x= 84<\/p>\n

Percentage of alcohol in\u00a0A = 60% => Let’s percentage of alcohol in B = x%<\/p>\n

The resultant mixture has 84% alcohol. ratio = 1:3<\/p>\n

Using allegations ,\u00a0$\\frac{\\left(x-84\\right)}{84-60}=\\frac{1}{3}$<\/p>\n

=> x= 92%<\/p>\n\n

7)\u00a0Answer:\u00a08<\/b><\/p>\n

Initially the amount of Dye and Water are 16,24 respectively.<\/p>\n

To make the ratio of Dye to Water to 2:5 the amount of water should be 40l for 16l of Dye=> 16l of water is added.<\/p>\n

Now, the Dye and Water arr 16,40 respectively.<\/p>\n

After removing 1\/4th of solution the amount of Dye and Water will be 12,30l respectively.<\/p>\n

To have Dye and Water in the ratio of 2:3, for 30l of water we need 20l of Dye => 8l of Dye should be added.<\/p>\n

Hence , 8 is correct answer.<\/p>\n

8)\u00a0Answer\u00a0(B)<\/strong><\/p>\n

Let ‘a’, ‘b’ and ‘c’ be the concentration of salt in solutions A, B and C respectively.<\/p>\n

It is given that\u00a0three salt solutions A, B, C are mixed in the proportion 1 : 2 : 3, then the resulting solution has strength 20%.<\/p>\n

$\\Rightarrow$ $\\dfrac{a+2b+3c}{1+2+3} = 20$<\/p>\n

$\\Rightarrow$ $a+2b+3c = 120$ … (1)<\/p>\n

If instead the proportion is 3 : 2 : 1, then the resulting solution has strength 30%.<\/p>\n

$\\Rightarrow$ $\\dfrac{3a+2b+c}{1+2+3} = 30$<\/p>\n

$\\Rightarrow$\u00a0$3a+2b+c = 180$ … (2)<\/p>\n

From equation (1) and (2), we can say that<\/p>\n

$\\Rightarrow$ $b+2c = 45$<\/p>\n

$\\Rightarrow$ $b = 45 – 2c$<\/p>\n

Also, on subtracting (1) from (2), we get<\/p>\n

$a – c = 30$<\/p>\n

$\\Rightarrow$ $a = 30 + c$<\/p>\n

In solution D, B and C are mixed in the ratio 2 : 7<\/p>\n

So, the concentration of salt in D = $\\dfrac{2b + 7c}{9}$ =\u00a0$\\dfrac{90 – 4c + 7c}{9}$ =\u00a0$\\dfrac{90 + 3c}{9}$<\/p>\n

Required ratio = $\\dfrac{90 + 3c}{9a}$ =\u00a0$\\dfrac{90 + 3c}{9 (30 + c)}$ = $1 : 3$<\/p>\n

Hence, option B is the correct answer.<\/p>\n

9)\u00a0Answer\u00a0(C)<\/strong><\/p>\n

The proportion of water in the first mixture is $\\frac{1}{3}$
\nThe proportion of Liquid A in the first mixture is $\\frac{2}{3}$<\/p>\n

The proportion of water in the second mixture is $\\frac{1}{4}$
\nThe proportion of Liquid B in the second mixture is $\\frac{3}{4}$<\/p>\n

The proportion of water in the third mixture is $\\frac{1}{5}$
\nThe proportion of Liquid C in the third mixture is $\\frac{4}{5}$<\/p>\n

As they are mixed in the ratio 4:3:2, the final amount of water is $4 \\times \\frac{1}{3} + 3 \\times \\frac{1}{4} + 2 \\times \\frac{1}{5} = \\frac{149}{60}$
\nThe final amount of Liquid A in the mixture is $4\\times\\frac{2}{3} = \\frac{8}{3}$
\nThe final amount of Liquid B in the mixture is $3\\times\\frac{3}{4} = \\frac{9}{4}$
\nThe final amount of Liquid C in the mixture is $2\\times\\frac{4}{5} = \\frac{8}{5}$<\/p>\n

Hence, the ratio of Water : A : B : C in the final mixture is $\\frac{149}{60}:\\frac{8}{3}:\\frac{9}{4}:\\frac{8}{5} = 149:160:135:96$<\/p>\n

From the given choices, only option C \u00a0is correct.<\/p>\n

10)\u00a0Answer\u00a0(C)<\/strong><\/p>\n

Let the volume of the cup be V.
\nHence, after removing three cups of alcohol from the first container,<\/p>\n

Volume of alcohol in the first container is 500-3V
\nVolume of water in the second container is 500 and volume of alcohol in the second container is 3V.
\nSo, in each cup, the amount of water contained is $\\frac{500}{500+3V}*V$<\/p>\n

Hence, after adding back 3 cups of the mixture, amount of water in the first container is $0+\\frac{1500V}{500+3V} $
\nAmount of alcohol contained in the second container is $3V – \\frac{9V^2}{500+3V} = \\frac{1500V}{500+3V}$<\/p>\n

So, the required proportion of water in the first container and alcohol in the second container are equal.<\/p>\n
