We have to use simple linear equation here. Let us keep Sharma weight as x .Weight lost by Sharma = 15/1x2 =30 kg
Weight gained by Sharma = 2/1 by 4 = 2/1 x4 = 8 kg Weight lost by Sharma = 3/3x4 = 4 kg . So x + 30 + 8+4 = 95 kg ; x+42=95; x=95-42 ; x= 53 kg. Thefore Sharma weight start to begin with 53 kg.
