Question

the product of two numbers is 528.if the product of their unit digit is 8 and the product of their ten digit is 4.find the numbers

Answer 1

Let the ten digit be x. Then, the unit be 8x
now, x+8x=528
9x=528
x=528/9
x= 48.67(approx.)
hence, the no. in tens digit=48.67 and no. in unit digit is 48.67×8= 389.36

Answer 2

Answer:

22 x 24 = 528

Step-by-step explanation:

Let the two numbers be Aa and Bb

Aa x Bb = 528  

ab = 8  

SO a = 2 and b = 4  

AB = 4

So A= 2 and B = 2

So the numbers are 22 and 24

ie 22 x 24 = 528
