A. (i)3.394(ii)2.035702(iii)0.002560 B. (i)3.383(ii)2.03702(iii)0.002561
C. (i)3.393(ii)3.03702(iii)0.002460 D. (i)3.393(ii)3.03702(iii)0.002560
Answer : D
Explanation :
(i) 261 8 13 = 3393.
Sum of decimal places of given numbers = (2+1) = 3.
2.61 * 1.3 = 3.393.
(ii) 21693 * 14 = 303702.
Sum of decimal places = (4+1) = 5
2.1693 * 1.4 = 3.03702.
(iii) 4 * 4 * 4 * 40 = 2560.
Sum of decimal places = (1 + 2+ 3) = 6
0.4 * 0.04 * 0.004 * 40 = 0.002560.
