Answer 1

Answer:

24

Step-by-step explanation:

let's take random numbers :-

ones digit be 1

tens digit =2×1=2 (according to question)

so number is 12 then add 18

12+18=30 (doesn't fulfill the condition of reversed digits)

So take one's digit=2

ten's digit= 2×2=4

so obtained number is 24

then add 18 so 24+18=42(fulfilling the condition of reversed digits)

Hence, 24 is the answer.
