Correct Answer:

A) 67 |

Description for Correct answer:

Let hundred's digit = x

Then unit's digit = 4x and ten's digit = 3x

Number = 100x + 30x + 4x = 134x

Again, hundred's digit = x

Ten's digit = 4x and unit's digit = 3x

Number = 100x + 40x + 3x = 143x

According to the question,

143x -134X = 18 => 9x = 18

x = 2

Original number = 134x = 134 x 2 = 268

25% of original number = \( \Large 268 \times \frac{25}{100} = 67 \)
