\(\frac{145}{229}\)
\(\frac{153}{220}\)
\(\frac{146}{225}\)
\(\frac{162}{227}\)
The simple interest on a certain sum for 3 \( \frac{5}{9} \) years at the rate of 2.7% per annum is ₹2,808.
What will be the amount payable on the same sum at the rate of 9.2% per annum simple interest in 5 \( \frac{2}{3} \) years?
Find the volume (in cm³) of a sphere having a diameter of 16.8 cm, giving your answer correct to two decimal places.
Take Π = \( \frac{22}{7} \).
The value of \(\sqrt{400}\) + \(\sqrt{0.0289}\)- \(\sqrt{7.84}\) =
Simplify: 3((\( \frac{6}{3} \))x² - 29x + 14) - 6(x² + 5x - 13)
The selling price of 50 books is equal to the cost price of 15 books. Find the loss or gain percentage on these books.
\( \frac{100}{35} \)% gain
70% loss
\( \frac{100}{35} \) % loss
70% gain
By how much is 65% of 75 greater than \( \frac{3}{5} \) of 35?
