If A is 95% of B, then what per cent of A is B?
\(110\dfrac{3}{19}\) %
\(104\dfrac{7}{19}\) %
\(108\dfrac{17}{19}\) %
\(105\dfrac{5}{19}\) %
A can complete a piece of work in 25 days while B can complete the same work in 30 days. They work on alternate basis, starting with A. Both A and B follow this pattern for 5 days and then A leaves the work. In how many days will B finish the remaining work?
\(24\dfrac{2}{5}\)
\(5\dfrac{2}{5}\)
\(5\dfrac{3}{5}\)
\(24\dfrac{3}{5}\)
8 men can complete a work in 45 days. 8 women can complete the same work in 18 days. In how many days will 5 men and 8 women, together, complete the same work?
\(13\dfrac{1}{5}\)
\(12\dfrac{4}{5}\)
\(14\dfrac{2}{5}\)
\(15\dfrac{3}{5}\)
625 + 626 + 627 + 628 is divisible by:
