Can you answer the one which is crossed and give me the soluution step by step please

Answer 1

Answer:

Option B (780)

Step-by-step explanation:

Let A - B = 255 be (1)

B - C = 275 be (2)

C - D = 250 be (3)

Now add both (1) and (2)

(A - B) + (B - C) = 255 + 275

A - B + B - C = 530

A - C = 530

Let A - C = 530 be (4)

Now add (4) and (3)

(A - C) + (C - D) = 530 + 250

A - C + C - D = 780

A - D = 780
