QUESTION: 13

When positive integer x is divided by positive integer y, the remainder is 9. If x/y = 96.12, what is the value of y

Solution:

The remainder is 9 when x is divided by y, so x = yq + 9 for some positive integer q.

Dividing both side by y give x/y = q + 9/y

But x/y = 96.12 = 96 + 0.12

Equating the two expressions for x/y give q + 9/y = 96 + 0.12

Thus q = 96 and 9/y = 0.12

⇒ 9 = 0.12y

⇒ y = 9/0.12

⇒ y = 75

QUESTION: 14

For all positive integers m and v, the expression m Θ v represents the remainder when m is divided by v. What is the value of ( (98 Θ 33) Θ 17 )− ( 98 Θ (33 Θ 17) ) ? 

Solution:

First for ((98 Θ 33) Θ 17), determine 98 Θ 33, which equalsd to 32, since 32 is remainder when 98 divided with 33 ( 98 = 2(33) + 32 ).

Then determine 32 Θ 17 which equals to 15, since 15 is the remainder when 32 is divided by 17( 33= 1(17) +15)

Thus ( (98 Θ 33) Θ 17 ) = 15

Next, for (98 Θ (33 Θ 17)) , determine 33 Θ 17, which equalsd to 16, since16is remainder when33 divided with17 ( 33 = 1(17) + 16 ).

Then determine 98 Θ 16 which equals to 2, since 2 is the remainder when 98 is divided by 16 ( 98 = 6(16) + 2)

Thus (98 Θ (33 Θ 17)) = 2

Finally  ((98 Θ 33) Θ 17)− (98 Θ (33 Θ 17)) = 15 - 2 = 13

 

QUESTION: 15

Solution:

1, 4, 7, 10, 13, 16, 19, 22, 25, 28, 31, 34, 37, 40, 43, 46, 49
A total of 17 numbers are there which gives a remainder 1 when divided by 3
