The table given below shows the number of players participating in two games in six different schools?
| Schools | Game A | Game B |
| J | 31 | 58 |
| K | 24 | 36 |
| L | 18 | 26 |
| M | 29 | 37 |
| N | 12 | 33 |
| P | 40 | 44 |
What is the ratio of total number of players participating in game A to the total number of players participating in game B?
â–³ABC is a right angle triangle at B. If tan A = \( \frac{5}{12} \), then sin A + sin B + sin C will be equal to:
\( 1 \frac{5}{13} \)
\( 2 \frac{4}{13} \)
\( 3 \frac{1}{13} \)
\( 2 \frac{1}{13} \)
Study the given triangle and find the length of BC.
The tax on the salary of C is \( \frac{1}{4} \) of the salary and savings are \( \frac{1}{3} \) of the salary. The ratio of the expenditures to the savings is_______.
Study the table and answer the questions.
A school has four sections A,B,C,D of class IX students.
The results of science and maths are shown in the table.
| RESULT | No. of Students | |||
| Section A | Section B | Section C | Section D | |
| Failed in both | 24 | 25 | 18 | 20 |
| Failed in Science but passed in Mathematics | 14 | 12 | 10 | 15 |
| Passed in Science but failed in Mathematics | 7 | 6 | 8 | 10 |
| Passed in both | 63 | 60 | 56 | 55 |
What is the ratio of number of students who failed in Science but passed in Mathematics of section B and section D together to the number of students of section A that passed in both subjects?
In a 1200 m race, bike A beats bike B by 100 m. Bike B beats bike C by 100 m in a 600 m race. If bike A beats bike C by 30 sec in a 720 m race, then what is the speed of bike C?
\( \frac{17}{3} \text{ m/sec} \)
\( \frac{26}{9} \text{ m/sec} \)
\( \frac{17}{9} \text{ m/sec} \)
\( \frac{26}{3} \text{ m/sec} \)
