Hello sir, thanks for keeping all of us motivated. I am preparing for CSE 2018 and have read NCERTS and quite a few books like Laxmikant and Ramesh singh. I am revising them currently, do I start looking into General Studies and optional or do I stick to this for now?

5% salt means 0.3 salt in 6l 5.7 water in 6l salt in 1l =0.05 water in 1l=0.95 so remaining salt = 0.3- 0.05=0.25 remaining water= 5.7-0.95=4.75 % of salt = 0.25/0.25+4.75*100= 5

ese mat kro 6 L = 6000 ML 5% of 6000 ML = 300 salt = 300 water = 5700 now 1 L water evaporated remaining water = 4700 salt = 300 salt % in solution of 5000 300/5000 * 100 = 6%
