Question

write the mathematical expression for, the sum of twist x and 4 is 24​

Answer 1

Answer:

Let the digit in the ones place be x and tens place be y

Hence the two digit number =10y+x

Given that the two digit number =4 times sum of its digits

According to the question,

⇒ 10y+x=4(x+y)

⇒ 10y+x=4x+4y

⇒ 3x−6y=0

⇒ x=2y ------- ( 1 )

It is also given that the two digit number =2 times product of its digits

⇒ 10y+x=2xy

Divide by xy both the sides, we get

⇒

x

10

y

1

=2

Put x=2y from (1), we get

⇒

6

=2

∴ y=3

⇒ x=2y=2(3)=6

⇒ The two digit number =(10y+x)=10(3)+6=36
