Answer 1

AnswEr :

• Let the Numbers be n, (n + 9), (n + 18)

A.T.Q.

➟ n + (n + 9) + (n + 18) = 81

➟ 3n + 27 = 81

➟ 3n = 81 - 27

➟ n = $\large\tt{\frac{54}{3}}$

➟ n = 18

━━━━━━━━━━━━━━━━━━━━━━━━

▣ Smallest Number = n = 18

▣ Second Number = (n + 9) = 18 + 9 = 27

▣ Third Number = (n + 18) = 18 + 18 = 36
