Question

A two digit number contains the smaller of the two digits at unit place. The product of the digits is 40 and the difference between the digits is 3.Find the number ​

Answer 1

Answer:

Step-by-step explanation:

let the digits are x and x+3

product=x(x+3)=40

x^2+3x-40=0

x2+8x-5x-40=0

x(x+8)-5(x+8)=0

(x+8)(x-5)=0

x=-8 or 5

but the digit can not be negative

so x=5

hence the digits are 5 and 8

and number=85
