In a survey of students, it was found that 50% of them like English, 60% like Maths and 40% like Science. If 20% like Maths and English, 15% like English and Science, 25% like Maths
and Science and 5% like all three subjects,
(1) What percentage of students like only two subjects ?
What percentage of students don't like any subject ?

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)

transitive property

step-by-step explanation:

the definition of the transitive property is:

if a = b, and b = c, then a = b
