Out of 25 children, 10 children like science subject and 15 children like English. 7 children like both the subjects.

Out of 25 children, 10 children like science subject and 15 children like English. 7 children like both the subjects. How many students don't like any subject?

7 children.

This can be solved by drawing a Venn diagram. The diagram is attached to this response.

Given:

Total number of children = 25

Number that like both subjects = 7

Number that like science = 10

Number that like English = 15

Unknown

Let the number of children that like science alone be s

Let the number of children that like English alone be e

Let the number of children that do not like any subject be x

s = Number that like science - number the like both subjects.

s = 10 - 7

s = 3

e = Number that like English - number the like both subjects.

e = 15 - 7

e = 8

Total number of children = Number that like science alone + Number that like English alone + Number that like both subjects + Number that do not like any subject.

This implies that;

25 = 3 + 8 + 7 + x

Solving for x gives;

25 = 18 + x

x = 25 - 18

x = 7

Therefore, 7 children do not like any subject.

step-by-step explanation:

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
