In an examination,40% students passed in Maths only,30% passed in Science only and 10% students failed in both the subjects. If 400 students passed in Science, find the total number of students by drawing a Venn diagram.

506.1

Step-by-step explanation:

The total number of students is 506.1 because 400 Plus 40% Plus 10% is what answer i got . But notice i said but - if im wrong you can always figure it out yourself

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.

the factors of 24 are 1, 2, 3, 4, 6, 8, 12 and 24. hope this ! mark brainliest! you v much! : )
