Question

A two digit number is four times the sum of its digits .if 27 were added to the number it becomes seven times the sum of digits. find the number .​

Answer 1

Answer:

36 is the answer

Step-by-step explanation:

Let the two digit number be(10x+y)

Given that,

10x + y = 4(x+y)

6x = 3y

y = 2x

According to the question,

(10x + y) + 27 = 7(x+y)

3x + 27 =6y

By putting y = 2x

x = 3

y = 6

Then the number is (10x + y) = 30 + 6 = 36
