Question

plz answer the 3rd and 4th question...

Answer 1

Answer:

3) Because 24y4 is a multiple of 9

therefore sum of digits= multiple of 9

2+4+y+4= multiple of 9

2+4+4+y= multiple of 9

10+y= multiple of 9

therefore, y could be equal to 8

because, 10+8= 18 , which is a multiple of 9

(you can take other number as well which would add up resulting a number which is a multiple of 9 but since its a 1 digit number, most probably it would be 8)

4)  because, 712z6 is a multiple of 9

therefore, sum of digits = multiple of 9

7+1+2+z+6= multiple of 9

7+1+2+6+z= multiple of 9

16+z= multiple of 9

here z could be 2

because 16+2= 18, which is a multiple of 9

(or it could be 9 as 16+9=27, which is a multiple of 9. Anyways you can choose which one you want to apply. Hope this helps!)
