Question

Ethan sold some watches at $14 each and 20 bookmarks at $1.50 each. Roy sold the same number of watches at $13.50 each and 20 bookmarks at $1.80 each. They collected the same amount of money. How many watches did Ethan sell?

Answer 1

Answer:

एथन = एक्स (14) + (20) (20) (1.50)

रॉय = एक्स (13.50) + (20) (1.80) बेची गई घड़ियों की संख्या

:

14x + (20) (1.50) = 13.50x + (20) (1.80)

शब्दों को

मिलाएं : 14x - 13.50x = (20) (1.80) - (20) (1.50)

0.50x = 36 - 30

0.50x = 6

x = 6 / 0.50

x = 12

एथन ने 12 घड़ियाँ
