Answer 1

Answer:

8

Step-by-step explanation:

If The Number '134X58Y' Is Divisible By 72, Find The Value Of (2X+Y) Is

The Number '134X58Y' Is Divisible By 72

72 = 8 * 9

134X58Y' Is Divisible By 8 if 58Y is divisible by 8

584 is divisible by 8

Y = 4

134X58Y' Is Divisible By 9 if sum is divisible by 9

=> 1 + 3 + 4 + X + 5 + 8 + Y is divisible by 9

=> 21 + X + 4  is divisible by 9

=> 25 + X is divisible by 9

=> X = 2  as 27 is divisible by 9

X = 2

2X + Y = 2*2 + 4 = 8

Answer 2

Answer:

Let last three terms is divisible by"8

So 584 is fully divisible by 8

Do y =4

1+3+4+x+5+8+4 is divisible by 9

So ,,

25+x is divisible by 9

So x =2

So

2x+y= 4+4=8
