Step-by-step explanation:
3*5=15 and 15-3=12. The product of 3 and 12 is 36.
Answer:
48
Step-by-step explanation:
48
Let the tens digit be x.
Hence, the units digit will be 2x
Number =10×(x)+(2x)=12x
When 36 is added to the number, the new number formed =12x+36
As the digits are reversed, we can also write the new number as 10×(2x)+x=21x
Hence,
12x+36=10×(2x)+x
⇒12x+36=21x
⇒21x−12x=36
⇒9x=36
⇒x=4
Hence, the original number =12x=12×4=48
-32 because all you do is multiply -2 5 times.
