Question

If A-B=255,B-C=275,C-D=250 then find A-D

Answer 1

Answer:

780

Step-by-step explanation:

A-B=255. ........ (1)

B-C=275. ........ (2)

C-D=250. ........ (3)

(1)+(2)+(3):

A-B+B-C+C-D=255+275+250

A-D=780

Answer 2

The correct answer is 780.

Given: The equations = A-B=255, B-C=275, C-D=250.

To Find: The value of A - D.

Solution:

A-B=255  (equation 1)

B-C=275  (equation 2)

C-D=250  (equation 3)

equation 1 + equation 2 +equation 3

A - B + (B-C) + (C-D) = 255 + 275 + 250

A - D = 780

Hence, the value of A-D is 780.
