There are 48 cards in a pack and each card is either red or black.
The ratio of the number of red cards to the number of black cards is 1:1
8 red cards are removed from the pack.
Find the ratio of the number of red cards now in the pack to the number of black cards now in the pack.
Give your answer in its simplest form.

The ratioof red cards to lack cards is 2:3

Step-by-step explanation:

SInce the ratio is 1:1 that means that there are 24 red cards and 24 black

Then 8 red cards are taken away, so 24-8=16

The new ratio from red to black is now 16:24

16:24 in the simplest for is 2:3

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
