What is the value of \( 56 - [36 - \{2 + 10 \times (6 - 3)\}] \)
What is the value of \( \frac{\frac{5}{6} - \frac{5}{11} \text{ of } \left[ \frac{3}{7} + \frac{8}{12} \div \frac{6}{24} + \frac{5}{7} \right]}{\frac{3}{12} \times \frac{6}{5}} \)
\( \frac{-1891}{691} \)
\( \frac{2075}{693} \)
\( \frac{-1894}{891} \)
\( \frac{-2075}{693} \)
The following table shows the number of trains that originate in the five different zones of the railway network of a country.
| Zone | Trains |
| Z1 | 690 |
| Z2 | 710 |
| Z3 | 830 |
| Z4 | 670 |
| Z5 | 900 |
The total number of trains that originate in Z3 and Z4 taken together is what percentage of the total number of trains that originate in all the 5 zones taken together?
The following pie chart shows the expenditure of a village in a given year in the different sectors of its economy.
If the amount spent on agriculture was ₹8.5 crore, then find the amount spent in the IT sector.
A sum of ₹3,400 is divided among P and Q in such a way that \( \tfrac{3}{4} \) of P's share is equal to \( \tfrac{2}{3} \)of Q's share. What is the positive difference between the shares of P and Q?
Profit earned on selling a book for ₹450 is the same as the loss incurred on selling it for ₹390. Find the cost price of the book.
The length, the breadth, and the height of a closed cardboard box are in the ratio of 5 : 3 : 7, respectively. Find the length of this box, if its total surface area is 1278 cm2
Train A crosses train B completely in 90 seconds, with the trains running in opposite directions. The lengths of the trains A and B are 900 metres and 1800 metres respectively. If the speed of train A is 45 km/h, then in how much time can train B cross a stationary pole?
\( \frac{830}{7} \text{ seconds} \)
\( \frac{810}{7} \text{ seconds} \)
\( \frac{720}{7} \text{ seconds} \)
\( \frac{650}{7} \text{ seconds} \)
