There is equal number of students in each of 10 classes in a school. In a day with bad weather, three classes are 1/2 full, 5 classes are 3/4 full and two classes 1/6 th empty. If the number of absent 6 students is 74 in that particular day, what is the total number of students in 10 class?

$Let, the company must sell x number of Frisbee to make break even.$

$According to question$

$7x = 10000 + 2x$

$= 7x - 2x = 10000$

$= 5x = 10000$

$\therefore x\frac{10000}{5}=2000$

The company must sell 2,000 Frisbee to make break even.

$Let, x be the maximum number of two points.$

According to question

$2x + (2 \times 3) = 26$

$= 2x + 6 = 26$

$= 2x = 26 - 6 = 20$

$\therefore x=\frac{20}{2}=10$

$(P + R + T) take 5 hours to fill up 1 \tan k$

$\therefore (P + R + T) take 1 hour to fill up \frac{1}{5} part of \tan k$

$Again, (P + R) take 7 hours to fill up 1 \tan k$

$\therefore (P + R) take 1 hour to fill up \frac{1}{7} part of \tan k$

$\therefore In 1 hour, T can fill up = (\frac{1}{5}-\frac{1}{7}) =\frac{7-5}{35}=\frac{2}{35} part of \tan k$

$Now, \frac{2}{35} of \tan k is filled by T in 1 hour$

$\therefore 1 or complete part of \tan k is filled by T in = \frac{35\times 1}{2} =17\frac{1}{2} hours$
