The house number is greater than 400 and less than 500. when you add 6 to the house number, the result ends in 0. the sum of the digits in the house is 13.

The last number needs to be 4, because when you add 6 it ends in 0 and 6+4 = 10

The first number is also 4 since it has to be between 400 and 500.

The sum of the numbers is 13, so the middle number would be 13-4-4 = 5.

The house number is 454

option (a)

step-by-step explanation:

step 1:   take 2 number whose product equal to 25..

and sum of those two number are -10

step: 2 for example here if we take 5,5 are the number,,

5*5=25

and

5+5=10

but we need -10

so if we take   -5,-5

so -5*-5=25

and -5+(-5)=-10

s0

come the equation

replace -10x by these number

like -5x -5x+25

take common

x(x-5)-5(x-5)=0

(x-5)(x-5)=0
