Answer» Solution : (i) Less than SERIES : We may prepare the less than series as under:  `"Scale":{{:("Along the X-axis,5 small div.",=1kg),("Along the Y-axis, 10 small div.",=5KG):}` We plot the points A(40,3),B(42,5),C(44,9),D(46,14),E(48,28),F(50,32) and G(52,35) . Join AB, BC, CD, EF, and FG with a FREE hand ot GET the cruve repressentingLess than series. (ii) More than Series : We many prepare the more series as under :  On the same grph-paper as above we plot the points P(38,35),Q(40,32), R(42,30), S(44,26),T(46,21), U (48,7) and V(50,3), . Join PQ,QR,RS, ST,TU,jand UV, with a free hadn to get cruve represnting 'More than sereis' `"Scale":{{:("Along the X-axis,5 small div.",=1kg),("Along the Y-axis, 10 small div.",=5"student"):}`  The two cruves intersect at tht point L. Draw `LMbotOX` `:.` Median weight = OM =46.5 kg |
