  1. A student got \(320\) marks out of \(500\) marks, find out percentage marks the student obtained?

    1. \(55 \ \%\)
    2. \(62 \ \%\)
    3. \(64 \ \%\)
    4. \(66 \ \%\)


Answer: (c) \(64 \ \%\)

Solution: Given, Total marks = \(500\), marks ontained by student = \(320\) then, $$ Percentage = \frac{Marks \ obtained}{Total \ Marks} \times 100 $$ $$ = \frac{320}{500} \times 100 = 64 \ \% $$

  1. If the difference between \(65 \ \%\) and \(45 \ \%\) of a number is \(500\), then find out the number?

    1. \(2300\)
    2. \(2500\)
    3. \(2800\)
    4. \(3000\)


Answer: (b) \(2500\)

Solution: Difference between \(65 \ \%\) and \(45 \ \%\) = \(500\)

\(65 \ \% - 45 \ \% = 500\)

\(20 \ \% = 500\) then

\(1 \ \% = 25\)

\(100 \ \% = 2500\), then the number is \(2500\)

  1. If \(20 \ \%\) of a number is \(600\), then find the \(35 \ \%\) of the number?

    1. \(1050\)
    2. \(1150\)
    3. \(1100\)
    4. \(1075\)


Answer: (a) \(1050\)

Solution: Given, \(20 \ \% = 600\) then

\(1 \ \% = 30\) and \(35 \ \% = 1050\)

  1. A man covers \(150 \ km\) out of total distance \(350 \ km\). Find the percentage distance the man covers?

    1. \(42 \ \%\)
    2. \(43.534 \ \%\)
    3. \(44.534 \ \%\)
    4. \(42.857 \ \%\)


Answer: (d) \(42.857 \ \%\)

Solution: Given, Total distance = \(350 \ km\)

The man covers the distance = \(150 \ km\) then, $$ Percentage = \frac{distance \ covered}{Total \ distance} \times 100 $$ $$ = \frac{150}{350} \times 100 = 42.857 \ \% $$

  1. If the income of Trump is \(50 \ \%\) more than that of Putin's income, then find out how much percent is Putin's income less than that of Trump's income?

    1. \(32.05 \ \%\)
    2. \(33.33 \ \%\)
    3. \(34.50 \ \%\)
    4. \(35.50 \ \%\)


Answer: (b) \(33.33 \ \%\)

Solution: Given, \(n = 50 \ \%\), then the Putin's income less than that of Trump's income is $$ \left[\frac{n}{100 + n} \times 100\right] \ \% $$ $$ = \left[\frac{50}{100 + 50} \times 100\right] \ \% $$ $$ = \frac{100}{3} = 33.33 \ \% $$

  1. Convert the fraction value \(\frac{5}{4}\) in to percentage value?

    1. \(125 \ \%\)
    2. \(130 \ \%\)
    3. \(150 \ \%\)
    4. \(110 \ \%\)


Answer: (a) \(125 \ \%\)

Solution: $$ = \frac{5}{4} \times 100 = 125 \ \% $$

  1. Convert the \(35 \ \%\) in to fraction value?

    1. \(0.36\)
    2. \(0.35\)
    3. \(0.25\)
    4. \(0.28\)


Answer: (b) \(0.35\)

Solution: $$ 35 \ \% = \frac{35}{100} = 0.35 $$

  1. If a man spent \(20 \ \%\) of his salary on food \(30 \ \%\) on home expenditure then find out total expenditure of his salary (in fraction)?

    1. \(0.7\)
    2. \(0.4\)
    3. \(0.5\)
    4. \(0.2\)


Answer: (c) \(0.5\)

Solution: Total percent the man spent of his salary = \(50 \ \%\)

then total expenditure (in fraction) $$ 50 \ \% = \frac{50}{100} = 0.5 $$ \(0.5\) part of his salary the man total spent.

  1. If a man spent \(\frac{2}{3}\) of his salary on dinner and \(\frac{1}{5}\) of his salary on shopping, then find how much percent of his salary he spent?

    1. \(85.68 \ \%\)
    2. \(84.67 \ \%\)
    3. \(82.68 \ \%\)
    4. \(86.67 \ \%\)


Answer: (d) \(86.67 \ \%\)

Solution: Total spent by the man $$ = \frac{2}{3} + \frac{1}{5} = \frac{13}{15} $$ in terms of percentage total expenditure $$ = \frac{13}{15} \times 100 = 86.67 \ \% $$

  1. A student obtained \(30\) marks out of \(70\) marks, then find the percentage marks the student obtained?

    1. \(43.56 \ \%\)
    2. \(42.85 \ \%\)
    3. \(45.75 \ \%\)
    4. \(44.52 \ \%\)


Answer: (b) \(42.85 \ \%\)

Solution: Given, Total marks = \(70\), marks obtained = \(30\), then $$ Percentage = \frac{marks \ obtained}{total \ marks} \times 100 $$ $$ = \frac{30}{70} \times 100 = 42.85 \ \% $$
