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

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

Let’s say marked price = 100
\nThen cost price = 64
\nand selling price = 88
\ndiscount = 24
\n%discount = $\\frac{24}{64} \\times 100$ = 37.5%<\/p>\n

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

Initially there were 100 blue balls, 50 red balls and 50 black balls.
\nAfter taking away there will remain 75 blue balls, 25 red balls and 50 black balls , a total of 150 balls
\nHence percentage of black balls will be $\\frac{50\\times100}{150}$ = $\\frac{100}{3}$<\/p>\n

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

let the length of rectangle be L units and breadth be B units.<\/p>\n

So area of rectangle = L x B<\/p>\n

As both length and breadth has been increased by 20%<\/p>\n

So new length = 1.2L<\/p>\n

New breadth = 1.2B<\/p>\n

New area = 1.2L x 1.2B = 1.44LB<\/p>\n

Percentage increase in area = $\\frac{1.44LB – LB}{LB}$\u00d7100 = 44%<\/p>\n

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

Let the cost price of 1 book be Rs C<\/p>\n

and the selling Price of 1 book be Rs S<\/p>\n

It is given that cost price of 100 books is equal to the selling price of 60 books<\/p>\n

So, 100xC = 60xS<\/p>\n

S = $\\frac{5}{3}$ C<\/p>\n

So Profit % = $\\frac{SellingPrice-CostPrice}{CostPrice}$x100<\/p>\n

= $\\frac{\\frac{5C}{3}-C}{C}$x100<\/span><\/p>\n

= $\\frac{2}{3}$ * 100 = <\/span>$66\\frac{2}{3}$ %<\/p>\n

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

let the income of person be Rs y<\/p>\n

So his expenditure be 75% of income which is = 0.75y<\/p>\n

Saving = y- 0.75y = 0.25y<\/p>\n

Now after increment of 20 % in income the new income becomes = 1.2y<\/p>\n

Given that bew expenditure is 10% more than previous one.So , new expenditure is = 1.1 \u00d7 0.75y = 0.825y<\/p>\n

New savings = 1.2y – 0.825y = 0.375y<\/p>\n

Percentage increase in savings =$\\frac {0.375y-0.25y}{0.25y}$\u00d7100 = 50%<\/p>\n

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

Let us assume that the fruit seller buys 100 oranges for Rs. 100
\nHe sells 40 oranges for Rs. 100
\nProfit obtained = 100 – 40 = Rs. 60
\n% Profit = $\\frac{60}{40} \\times 100 = 150$%
\nNow, he sells 80% of the remaining oranges at half the profit
\ni.e., he sells 48 oranges at 75% profit.
\nSelling Price of 48 oranges = 48 + 75% of 48 = Rs. 84
\nRest of them are thrown away.
\nTotal SP = 100 + 84 = 184
\nProfit = 184 – 100 = 84
\n% Profit = 84%<\/p>\n

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

Let the number of boys be 2y and number of girls be 3y<\/p>\n

25 % of boys = 0.25 x 2y = 0.5y<\/p>\n

30% of girls = 0.3 x 3y = 0.9y<\/p>\n

total scholarship holder = 0.5y + 0.9y = 1.4y<\/p>\n

% of no scholarship holder = $\\frac{3.6y}{5y}$ x 100 = 72%<\/p>\n

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

let the retailer buys 110 gram in Rs 100 because of 10 % cheating<\/p>\n

so cost price = 1 gram = Rs 100\/110 = Rs 0.909<\/p>\n

and retailer sells 90 gram in Rs 100<\/p>\n

and hence selling price = Rs 100 \/ 90 = Rs 1.111<\/p>\n

Profit % = $\\frac{1.111- 0.909}{0.909}$ = 22.22%<\/p>\n

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

it is given that<\/p>\n

0.3 A + 0.4 B = 0.8 B<\/p>\n

0.3 A = 0.4 B<\/p>\n

A = 4\/3 B<\/p>\n

B = 3\/4 A<\/p>\n

hence B is 75 % of A<\/p>\n

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

let the cost of a banana be Rs b<\/p>\n

and hence cost of an apple = 2b<\/p>\n

and guava cost be = 4\/3 b<\/p>\n

now cost of every fruit is increased by 10%<\/p>\n

and hence<\/p>\n

cost of a banana be Rs 1.1b<\/p>\n

and hence cost of an apple = 2.2 b<\/p>\n

and guava cost be = (4.4\/3)b<\/p>\n

initially , 4 bananas + 2 apples + 3 guavas = 13\/3 b<\/p>\n

finally ,\u00a04 bananas + 2 apples + 3 guavas = 14.3\/3 b<\/p>\n

and hence percentage increment = $\\frac{(14.3-13)}{13}$ x 100 = 10 %<\/p>\n\n
