Question

A two-digit number is four times the sum of its digits and is also equal to thrice the product of its digits.find the number

Answer 1

Hey,
Let the two digit number be 10(x+y),
10(x+y)=4(x+y)
10x+10y=4x+4y
6x+6y=0->equation one

Now, second equation..
10(x+y)=3*xy
10x+10y=3xy
10x+10y-3xy=0.

Now, solve both the equations to get ur answer..
