Answer 2

Question:

• In a two digit number, the digit in the tens place is three times the digit in the units place. If the digits are reversed, the number decreases by 36. Find the number.

Answer:

Let the digit in the units place be x. Then,

Digit in tens place = 3x

The number = 10(3x) + 1(x)

= 30x + x

= 31 x

After reversing the number = 10(x) + 1(3x)

= 10x + 3x

= 13x

A/q,

$\mathtt{\implies 31 x - 36 = 13x}$

$\mathtt{\implies 31x - 13x = 36}$

$\mathtt{\implies 18x = 36}$

$\mathtt{\implies x = \frac{36}{18}}$

$\mathtt{\implies x = 2}$

Hence, Units place digit = x = 2

Tens place digit = 3x = 3×2 = 6

And the number = 62

Extra Information:

• An equation is a statement of equality which contains one or more unknown variables.
• There are many methods to slove an equation. Some are:

1. Trial and Error Method
2. Systematic Method
3. Transposition
