Question

Keeping the significant figures in view, the sum of the physical quantities 52.01m, 153.2 m and 0.123 m is :

G1 Physics · Accepted Answer

Add the measured quantities: 52.01 + 153.2 + 0.123 = 205.333 m. For addition, the result must be rounded to the least number of decimal places present in the given measurements. The least precise measurement is 153.2 m, which is given to one decimal place. Therefore, 205.333 m must be rounded to one decimal place: 205.3 m. Correct option: D.
