Step-by-step explanation:

Let number of adults be x

Since, total number of persons is 50

Number of children = 50-x

Ticket rate for a child is 10 rupees

∴ ticket rate of 50-x children = 10(50-x) = 500-10x rupees

Ticket rate of an adult is 26 rupees

∴ ticket rate of x adults = 26x rupees

Total amount collected = 740 rupees

⇒ 26x + 500-10x = 740

⇒ 16x + 500 = 740

⇒ 16x = 740-500

⇒ 16x = 240

⇒x = 240/16

⇒x = 15
