Question

4. If x, x – 2 and 3x are in AP, then the value of x is:
(A) -3
(B) -2
(C) 3
(D)
5. x- axis divides the join of A(2, -3) and B(5, 6) in the ratio:
(A) 1:2
(B) 2: 1 (C) 3:2
(D) 2:3​

Answer 1

ANSWER

4)B

5)A

EXPLANATION

4) As they are in AP

2(x-2)= x+3x

2x-4 = 4x

2x = -4

x = -2

5)At x axis [y=0]

[(6m-3n)÷(m+n)]=0

6m=3n

2m=n

m:n =1:2
