Question

What is the answer here ???​

Answer 1

a + b + c = 8 ⇒ answer E

Explanation:

∵ 3b is a number with unit digit 2

∴ Let 3b = 12 ⇒ b = 4

∵ a < b ⇒ 3a + 1 = 4 ⇒ 3a = 3

∴ a = 1

∴ abb = 144

∴ abb + abb + abb = 144 + 144 + 144 = 432

∵ abb + abb + abb = bc2

∴ c = 3

∴ a + b + c = 1 + 4 + 3 = 8
