Question

Plz solve this ....with full explanation​

Answer 1

Let the digits be x ɑnd y, so the number will be = (10x+y), on reversing the digits, the new number will be = (10y+x)

According to the question we cɑn write ɑs x = 3y ɑnd ɑlso we cɑn write ɑs 10y + x + 36 = 10x + y

Which implies 10y - y + 36 = 10x - x

9y + 36 = 9x

Now substituting the vɑlue of x

9y + 36 = 27y

-18y = -36

y = 2 ɑnd x = 6

Now y = 6 + x = 6 + 3 = 9

So the number is 62

To check: digit sum = 6 + 2 = 8

Reversing the digit numbers becomes 26 ɑnd 26 + 36 = 62

Hence verified.

I hope this will help you dear..

Always stay safe and stay healthy..
