Q.no.1 Seven times a two-digit number is equal to four times the number obtained by reversing the digits. If the difference between the digits is 3. Find the number.
ANSWER
Let numbers be x at onces place & y at tens place so,
10y+x is the digit.
Reversed digit =10x+y
According to the question ,
∴7(10y+x)=4(10x+y)
⇒x=2y⟶(i)
Now,
Given , x−y=3
from equation (i)2y=x substitute in above equation.
2y−y=3
y=3
So ,
x=2y=2⋅3=6
∴ Required original no: is =10y+x=10⋅3+6=36.
