If x = y = z , then b + c c + a a + b
-
-
x − y = y − z = z − x b − c c − b a − c -
x = y = z a b c -
x − y = y − z = z − x c b c - None of the above is true
-
Correct Option: A
| = | |||
| b + c | b + a |
| = | = | ; | = | ||||
| b + c - c -a | b - a | c + a | a + b |
| = | = | ; | = | ||||
| c + a - a - b | c - b | a + b | b + c |
| = | = | ||
| a + b - b - c | a - c |
| ∴ | = | = | |||
| b - a | c - b | a - c |
