Question

If x =(50 ± 1)m y=(100± 2)m then y-x=……………….. A) (50 ± 1)m B) (50 ± 3)m C) (150 ± 1)m D)(12±0.3)m

Answer 1

To find the value of y-x, subtract the value of x from the value of y. Given x =(50 ± 1)m and y=(100± 2)m, y-x= 53 m.

Step-by-step explanation:

To find the value of y-x, we subtract the value of x from the value of y.

Given x =(50 ± 1)m and y=(100± 2)m, we subtract the smaller value of x (49) from the larger value of y (102) to get y-x= 102 - 49 = 53 m.

Therefore, the correct answer is (50 ± 3)m (Option B).
