true or false​

Answer 1

Answer:

False

Step-by-step explanation:

This question is quiet simple nothing to calculate, just we have to verify the given condition.

here the fact to verify is , 5 years ago

age of A is x-5

and age of B is 85-x   ,

(with the condition that 5 years ago the A was thrice as old as B)

ie., Check A = 3B

here     x-5 and 85-x

3(85-x) = 255-3x ≠ x- 5 for any given value of x

hence the statement given is False
