Question

(v) The sum of the digits of a two-digit number is 8. If its digits are reversed the
new number so formed is increased by 18. The number is
(a) 37
(6) 48
(c) 35
(d) 46​

Answer 1

Step-by-step explanation:

It is given that sum of the digits,that is x and y, is 8. Therefore we can state, x+y = 8. When we reverse (xy) it becomes (yx), in expanded form it can be written as (10y + x). Again it is given that difference between the two numbers is 18.
