Question

A two-digit number read from left to right is 20% greater than the same number read from right to left. Find the number.

Answer 1

Answer:

54

Step-by-step explanation:

We'll call the number "ab".

From left to right, the value of this number will be $10a+b$.

From right to left, the value of this number will ve $10b+a$.

From the question,

$10a+b=1.2(a+10b)\\10a+b=1.2a+12b\\8.8a=11b$

For a and b to be whole numbers,

$\left \{ {{a=5} \atop {b=4}} \right.$

So the number is 54.
