Question

in the group of 15 people 7 read malayalam 8 read English while 3 of them read none of these two how many people are reading malayalam and English both​

Answer 1

Answer:

3people

Step-by-step explanation:

so first of all 3 read none..

so subtract 3 from 15

15-3=12

now you can subtract any ( English speakers or malayam speakers )

I am taking 7, I. e. Malayalam speakers

so, 12-7 = 5

now use the no. language speakers left ( which we have not used till now)

we have to subtract 5 from that no. of speakers left.

so, 8 - 5 = 3

therefore 3 people speak both..
