9literate out of them 6 female literate

remaining literate are man 9-6=3

n

total male =20-8=12

illiterate male =12-3=9

Answer 2

Given:

✰ Total number of adults in the group = 20

✰ Total females in the group = 8

✰ Total literates adults in the group = 9

✰ Total female literates in the group = 6

To find:

✠ The number of male illiterates in the group.

Solution:

❖ Let's understand the concept! We know that Total number of adults in the group are 20 and total number of females in the group are 8, so to find total male members in the group we will substract total number of females in the group from Total number of adults in the group. The result we obtain will be total number of males in the group. After that we know that total literate adults in the group are 9 out of which 6 are female literates in the group so to find male literates in the group we will substract female literates from total literates adults in the group. Now, at last we will substract male literates in the group which be found earlier from total number of males and find the number of male illiterates in the group.

Let's find out...

⟹ Total number of adults in the group = 20

⟹ Total females in the group = 8

⟹ Total males in the group = Total number of adults in the group - Total females in the group

⟹ Total males in the group = 20 - 8

⟹ Total males in the group = 12

Now,

⟹ Total literates adults in the group = 9

⟹ Total female literates in the group = 6

⟹ Total male literates in the group = Total literates adults in the group - Total female literates in the group

⟹ Total male literates in the group = 9 - 6

⟹ Total male literates in the group = 3

Then,

➤ Total males in the group = 12

➤ Total male literates in the group = 3

➤ Total male illiterates in the group = Total males in the group - Total male literates in the group

➤ Total male illiterates in the group = 12 - 3

➤ Total male illiterates in the group = 9

∴ The number of male illiterates in the group = 9
