The area of a circle is 2464 cm². What is the diameter of this circle? \( \text{use } \pi = \frac{22}{7} \)
study the given pie-chart and answer the question that follows.
The following pie chart shows the sectors representing the shares of the number of chairs produced in a given year of each of six different brands in terms of the central angles (in degrees) with respect to the total number of chairs produced in that year of all the six brands taken together.
If the total number of chairs produced of these six brands taken together is 7200, then what is the total number of chairs produced of brands B2 and B3 taken together?
K1 can do a piece of work alone in 4 days, K2 can do the same work alone in 8 days, while K3 can do it alone in 32 days. They work together and complete the work, and receive a total of ₹,900 as payment for doing the work. What is the share of the person who received the maximum amount?
What is the value of \( \frac{7}{11} \div \frac{21}{33} \times \frac{5}{12} + \frac{10}{36} \times \frac{6}{11} \div \frac{18}{33} \) is:
\( \frac{29}{35} \)
\( \frac{25}{36} \)
\( \frac{28}{39} \)
\( \frac{24}{41} \)
