By the section formula, the point dividing A(a) and B(b) internally in the ratio m:n is?
A(mb + na)/(m + n)
B(ma - nb)/(m - n)
C(mb - na)/(m - n)
D(ma + nb)/(m + n)
Answer & Solution
Correct answer: A. (mb + na)/(m + n)
For internal division m:n the weight m goes on b and n on a, giving (mb + na)/(m + n).
