Let the digit in one's place be " x "
Ten's digit be " y "
So , Two digit number be , " 10 y + x "
A/c , " The number that has tens digit place, double the one place "
⇒ y = 2x ... (1)
A/c , " sum of the digits is 6 "
⇒ x + y = 6
⇒ x + ( 2x ) = 6 [ From (1) ]
⇒ 3x = 6
⇒ x = 2
Sub. x value in (1) , we get ,
⇒ y = 2(2)
⇒ y = 4
So , the number = 10(4) + 2 = 42
Answer:
Very easy its 42..........
