Answer 1

????????????????????????

Answer 2

Answer:

30

Step-by-step explanation:

let A = people speaking Sharchop and B  = people speaking Khengkha

Given:  n(A) = 70, n(B) = 60, n(A U B) = 100

n(A ∩ B) = n(A) + n(B) - n(A ∪ B)  // n(A ∩ B) = people speaking both Sharcop and Khenkha

= 70 + 60 - 100

= 30
