Answer 2

Answer:

To solve this question, we have to clear our concepts related to ratio and percentage.

For example:

Percentage= ratio × 100

Explanation:

Total number of seats: 1200

Types of seats: Balcony & stall

adult : children = 3:5

adult : total = 3:8

similarly, children: total = 5:8

children in stall = 2/15 of total children

children in balcony = 468

it means = 13/15 of total children = 468

let the number of total children be x

$\frac{13}{15} \times x = 468 \\ x = 468 \times \frac{15}{13}$

$x = 15\times 36$

$x = 540$

total number of children = 540
