Question

A two digit number is obtained by mutiplying the sum of the digit by 8 also it is abtained by mutiplying the difference of the digit by 14 and adding 2 find the number​

Answer 1

Answer:

Let two digit number be 10x+y

Given 10x+y=(x+y)8−−−−−−−−(1)

⟹14∣x−y∣+2=100x+y, let x>y

⟹14(x−y)+2=10x+y

⟹4x−15y+2=0−−−−−−−−(2)

from (1) 2x=7y−−−−−−−−(3)

From (2) & (3)

14y−15y+2=0

y=2

When y=2,x=7

So number is 72.
