Question

A two digit number is 4 times the sum of its digits and also 16more than the product of digits. find the number​

Answer 1

Step-by-step explanation:

10x+y=4(x+y)=x ×y+16

10x+y=4x+4y

6x=3y

2x=y

10x+2x=xy+16

12x=2x^2+16

tak8ng 2 common we get

2(x^2-6x+8)

2(x^2-4x-2x+8)

2[(x-4)(x-2)] by cimparing

therefore,the no. is x is 8 and y is 4

84 or 48 ,lets compare with .1

10×4+8=4(4+8)

hence the required no. is 48.

Answer 2

10x+y=4(x + y)=x ×y+16

10x+y=4x+4y

6x=3y

2x=y

10x+2x=xy+16

12x=2x^2+16

taking 2 common we get

2(x^2-6x+8)

2(x^2-4x-2x+8)

2[(x-4)(x-2)] by comparing

therefore, the no. is x is 8 and y is 4

84 or 48 ,lets compare with .1

10×4+8=4(4+8)

hence the required no. is 48.
