10 cost. 20 rupees ticket

Answer 2

Answer:

10 boys took 20 rupees ticket.

Step-by-step explanation:

Let x be the number of boys who take 20 rupees ticket and y be the number of boys who take 45 rupees ticket,

Since, the total number of boys = 50,

⇒ x + y = 50 --------(1)

Also, the combined price of tickets is 2000 rupees,

⇒ 20 x + 45 y = 2000 -------(2)

Equation (2) - 45 × Equation (1),

20 x - 45 x = 2000 - 2250

-25 x = - 250

⇒ x = 10

Hence, the number of boys who took 20 rupees ticket is 10.
