Question

a two digit number is less than 40 but greater than 30 the sum of the digits is equal to the half of their product what is the number
​

Answer 1

Answer:

Step-by-step explanation:

you can solve this problem using hit and trial method

you have to just check for the numbers between 31 to 39

suppose if i took 31 then

sum of digits is =4 and product of digit is 3 so 4 is not equal to 3/2

so move forward and check another

at 36 you will reach your answer

3+6=9 and product is 18 which is double  of digit's sum.

so ans is 36.
