Question

the digit in the units place of a two digit number is twice the digit in its tens place . the quotient obtained when the number is divided by the sum of its digits is 4 . find the number​

Answer 1

Answer:

Step-by-step explanation:

GIVEN,

Let 10th place digit = x

Unit place digit = 2x

Number

10x + 2x

= 12x

sum of digits

= x + 2x

= 3x

12x/3x

=4

4 = 4

so,

x may be 1,2,3,4.

Answer 2

The number is 12

GIVEN

The digit in the units place of a two digit number is twice the digit in its tens place . The quotient obtained when the number is divided by the sum of its digits is 4.

TO FIND

The number.

SOLUTION

We can simply solve the above problem as follows;

Let the digit at tens place by x and the digit at ones place be y

So the number = 10x + y

It is given,

y = 2x

Now,

The number = 10x + 2x

Sum of digits = x + 2x = 3x

ATQ,

$\frac{10x + 2x}{3x} = 4$

Solving for x

12x = 12x

x = 1

The value of x = 1

Value of y = 2x = 2×1 = 2

The two-digit number = xy = 12

Hence, The number is 12
