Question

in a row, A is 17th from the left and B is 19th from the right. If both interchange their places, A becomes 24th from the left. What is the total no of people in the row?

Answer 1

$\bf{\huge{\underline{\mathfrak{\red{Answer}}}}}$

• New position of B from right side = Position of B from right side before interchanging + (Position of A from left side after interchanging – Position of A from left side before interchanging)

⇒ New position of B from right side = 19 + (24 - 17)

= 18 + 4 = 22nd

• Total no. of persons = (A’s position from right before interchanging + A’s position from left before interchanging) – 1)

⇒ Total no. of persons = (B’s position from right after interchanging + A’s position from left before interchanging) – 1

⇒ Total no. of persons

= (19 + 17) – 1

= 36 - 1

= 35

•°• Total number of people in that row is 35.

Answer 2

Answer:

42

Step-by-step explanation:

@monkeyking1

After interchanging position of B becomes position of A,

before interchange - B is at 19th from right

after interchange A goes to B's position that is given - 24th from left.

Total people = 24 + (19-1) = 24 + 18 = 42.

Tell me why you're saying 35.
