1). What is 5% of 50% of 500?
5% of 50% of 500 | ||||

2). 89% of ? + 365 = 1075.22
89% of ? + 365 = 1075.22 = \( \Large \frac{89}{100} \times ? = 1075.22 - 365 \) Therefore, \( \Large ? = \frac{71022}{89} \) = 798. | ||||

3). What is 32% of \( \Large \frac{3}{8} \)th of 5000?
32% of E of 5000 | ||||

4). 12 of 26% of \( \Large \frac{5}{78} \) of 38% of \( \Large \frac{7}{152} \) of 10000 = ?
\( \Large 12 \times \frac{26}{100} \times \frac{5}{78} \times \frac{38}{100} \times \frac{7}{152} \times 10000 \) | ||||

5). A number increased by \( \Large 137\frac{1}{2} \)% and the increment is 33. The number is
Let the number be x. | ||||

6). A person's salary has increased from Rs.7200 to Rs.8100. What is the percentage increase in his salary?
Percentage increase in salary = \( \Large \frac{8100-7200}{7200} \times 100 \) \( \Large \frac{900}{7200} \times 100 = \) = 12.5% | ||||

7). A's salary is 20% less than B's salary. Then B's salary is more than A's salary by
Given, a = 20% | ||||

8). If the price of petrol is increased by 20%, by what percentage should the consumption be decreased by the consumer, if the expenditure on petrol remains unchanged?
Here, a = 20% Required percentage loss = & 100+ a X1009 = \( \Large \frac{a}{100+a} \times 100\% \) = \( \Large \frac{20}{100+20} \times 100\% \) = \( \Large \frac{20}{120} \times 100\% = 16\frac{2}{3}\% \) | ||||

9). If A's income is \( \Large \frac{5}{6} \)th of B's income, then B's income is more than A's income by
Given, \( \Large A = \frac{5}{6} B \) Let income of B = x Therefore, \( \Large A = \frac{5}{6}x \) Required percentage = \( \Large \frac{x-\frac{5x}{6}}{\frac{5x}{6}} \times 100 \) = \( \Large \frac{6x-5x}{5x} \times 100 \) | ||||

10). 25% of what amount of money is equal to \( 12\frac{1}{2} \)% of Rs.180 = ?
Let required amount of money be x. Then, \( \Large x \times 25\% = 180 \times 12\frac{1}{2}\% \) Therefore, x = \( \Large \frac{180 \times 125}{25} \) = Rs.90 |
