An amount is deposited at 8% p.a. compound interest. If the first year interest is Rs.72, find the interest amount for the 2nd year.
N has Rs. p more than K. The total amount available with N and K together is Rs. q. How much does K have?
\( \frac{q}{2} \) + p
2(p + q)
\(\frac{p+q}{2}\)
\(\frac{q-p}{2}\)
Find the value of 'x' in x : \( \frac{3}{7} \) :: \( \frac{7}{9} \) : \( \frac{5}{9} \)
\( \frac{4}{7} \)
\( \frac{3}{2} \)
\( \frac{3}{5} \)
\( \frac{9}{7} \)
