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?
\(32.05 \ \%\)
\(33.33 \ \%\)
\(34.50 \ \%\)
\(35.50 \ \%\)
Answer: (b) \(33.33 \ \%\)Solution: Given, \(n = 50 \ \%\), then the Putin's income less than that of Trump's income is $$ \left[\frac{n}{100 + n} \times 100\right] \ \% $$ $$ = \left[\frac{50}{100 + 50} \times 100\right] \ \% $$ $$ = \frac{100}{3} = 33.33 \ \% $$
Convert the fraction value \(\frac{5}{4}\) in to percentage value?
If a man spent \(20 \ \%\) of his salary on food \(30 \ \%\) on home expenditure then find out total expenditure of his salary (in fraction)?
\(0.7\)
\(0.4\)
\(0.5\)
\(0.2\)
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.
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?
\(85.68 \ \%\)
\(84.67 \ \%\)
\(82.68 \ \%\)
\(86.67 \ \%\)
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 $$ = \frac{13}{15} \times 100 = 86.67 \ \% $$
A student obtained \(30\) marks out of \(70\) marks, then find the percentage marks the student obtained?
\(43.56 \ \%\)
\(42.85 \ \%\)
\(45.75 \ \%\)
\(44.52 \ \%\)
Answer: (b) \(42.85 \ \%\)Solution: Given, Total marks = \(70\), marks obtained = \(30\), then $$ Percentage = \frac{marks \ obtained}{total \ marks} \times 100 $$ $$ = \frac{30}{70} \times 100 = 42.85 \ \% $$
