Answers & Solutions:<\/strong><\/span><\/p>\n

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

Let the cost price be 10x<\/em> and selling price be 11x<\/em><\/p>\n

Percentage Profit = $\\frac{11x – 10x}{10x}$ x 100 = 10<\/p>\n

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

Given: Profit = 12%
\nDiscount on printed price = 10%
\nLet’s say cost price is $x$ and printed price is $y$
\nhence sold price will be $x$ + $\\frac{12x}{100}$ and $y$ – $\\frac{10y}{100}$
\nBoth should be equal:
\nhence\u00a0$x$ + $\\frac{12x}{100}$ =\u00a0$y$ – $\\frac{10y}{100}$
\n$\\frac{x}{y}$ = $\\frac{45}{56}$<\/p>\n

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

Given:
\nRatio of two numbers = 3:5
\nHence we can say first number is $3x$ and second number is $5x$
\nProduct of two numbers is = 2160
\nor $15x^{2}$ = 2160
\nor $x$ = 12
\nhence numbers will be 30 and 60<\/p>\n

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

Given: ratio of A and B is 3:2 and total money to be divided 1000
\nlet’s say A received $3x$ and B received $2x$
\nhence\u00a0\u00a0$3x$ +\u00a0\u00a0$2x$ = 1000
\nor\u00a0$x$ = 200
\nhence A will receive 600<\/p>\n

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

Given: Terms are in ratio 7:11
\nlet’s say first term $7x$ and second term $11x$
\nadding $y$ to each term, it will be\u00a0$7x+y$ and\u00a0$11x+y$
\nand its ratio will be 3:4
\nhence\u00a0$7x+y$ :\u00a0$11x+y$ =\u00a03:4
\non solving above equation we get $5x$ = $y$
\nhence adding number should be a multiple of 5.
\nanswer will be (D)<\/p>\n

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

Let’s say numbers are $7x$ and $11x$
\nadding 7 to each of them
\nhence\u00a0$\\frac{7x+7}{11x+7}$ =\u00a0$\\frac{2}{3}$
\nor $x$ = 7
\nsmaller digit will be 49<\/p>\n

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

As we know cost price + profit = selling price
\nlet’s say cost price is $x$
\nas profit is 200% on cost price it will be $2x$
\nhence selling price will be 3x and ratio of cost price to selling price will be 1:3<\/p>\n

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

In first container quantity of milk relative to water is $\\frac{5}{3} \\times100$ = 166.65%
\nIn second container quantity of milk relative to water is\u00a0$\\frac{2}{1} \\times100$ = 200%
\nIn third container quantity of milk relative to water is\u00a0$\\frac{2}{1} \\times100$ = 150%
\nIn fourth container quantity of milk relative to water is\u00a0$\\frac{7}{4} \\times100$ = 175%
\nhence third container has least ratio<\/p>\n

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

let’s say one number is $x$ and another is $3x$
\nsummation will be $4x$ = 240
\n$x$ = 60
\nhence number will be 60 and 180
\nand difference will be 120.<\/p>\n

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

let’s say income is $11x$ and expenditure is $10x$ hence saving will be $x$
\nso when saving is $x$, annual income is\u00a0$11x$
\nnow when saving is 9000 , annual income will be\u00a0\u00a099000
\nand monthly income will be 8,250<\/p>\n\n
