Akhil can complete a piece of work in 26 days. Sakshi and Akhil both can complete the same work in 20 days. They started together but Sakshi left after working for 6 days. Find the number of days in which Akhil will complete the remaining work.
\( \frac{55}{4} \) days
\( \frac{89}{5} \) days
\( \frac{12}{5} \) days
\( \frac{91}{5} \) days
If the radius of the base and the height of a cylinder are 17cm and 49 cm respectively, then what is the curved surface area of the cylinder? (Use π =\( \frac{22}{7} \))
Find the value of y in the expression 2\( \frac{3}{7} \) × [(11\( \frac{2}{6} \) ÷ (\( \frac{25}{18} \) + 2\( \frac{5}{6} \) − \( \frac{7}{36} \)))] = y ÷ 72.5 × 204.
\( \frac{21}{5} \)
\( \frac{19}{3} \)
\( \frac{17}{7} \)
\( \frac{15}{2} \)
