sum of digits of a number is 6 if 36 is added to the number its digits are reversed determine the number

Answer»

★ Ello ★

here is your answer !!


let the UNIT digit be y


let the tens digit be x


according to question :-

sum of digit's is. 6


then ,

x + y = 6 -------------------(1)






NUMBER formed is => 10 x + y



again , digit's are reversed =>

10 y + x


now , according to question


10 x + y + 36 = 10 y + x


=> 9 ( x -y) = -36


x - y = -4. -----------------------(2)



from EQUATION 1 and 2 we get




x+ y = 6
x - y = -4
=========

2x = 2

x = 1


therefore , y = 5


hence , the number is 10 x + y


=> 10 × 1 + 5

=> 15



hence , your answer is 15



hope it helps you DEAR !!


thanks
