JEE Main 9 January 2020, Shift 2, Physics Q1

Question 1 of 75 in this shift, Physics question 1 of 25, Section A. NTA dropped this question from the final key; it is left out of every count on this site.

For the four sets of three measured physical quantities as given below. Which of the following options is correct ? (i)

A_1 = 24.36,\ B_1 = 0.0724,\ C_1 = 256.2

(ii)

A_2 = 24.44,\ B_2 = 16.082,\ C_2 = 240.2

(iii)

A_3 = 25.2,\ B_3 = 19.2812,\ C_3 = 236.183

(iv)

A_4 = 25,\ B_4 = 236.191,\ C_4 = 19.5

(1) $A_1+B_1+C_1 < A_3+B_3+C_3 < A_2+B_2+C_2 < A_4+B_4+C_4$
(2) $A_1+B_1+C_1 = A_2+B_2+C_2 = A_3+B_3+C_3 = A_4+B_4+C_4$
(3) $A_4+B_4+C_4 < A_1+B_1+C_1 = A_2+B_2+C_2 = A_3+B_3+C_3$
(4) $A_4+B_4+C_4 < A_1+B_1+C_1 < A_3+B_3+C_3 < A_2+B_2+C_2$
