Let, no. of chocolate = x ,no. of banana = y,& no. of coconut =z therefore x+y+z=100----------------eqn(1) 1 banana=1 rupees , 1chocolate=5/100=1/20 rupees , 1 coconut=5 rupees a/q, 1/20x+y+5z=100 or, x+20y+100z=2000-------------eqn(2) or, (100-y-z)+20y+100z=2000 ----------------------from eqn(1) or, 99z+19y=1900 or, 80z+19z+19y=1900 or, 80z+19(y+z)=1900 or, 80z+19(100-x)=1900 or, 80z-19x=0 x/z=80/19 so, when x=80,then z=19 it means when x is less than 80 then z will be in fraction which is not possible ,because x,y,z are numbers of things .or if x is greater than 80 then z will be in fraction. therefore x =80 ,z=19,y=1

Let, no. of chocolate = x no. of banana = y no. of coconut =z therefore x+y+z=100----------------(1) 1 banana=1 rupees 1chocolate=5/100=1/20 rupees 1 coconut=5 rupees 1/20x+y+5z=100 ⇒ x+20y+100z=2000-------------eqn(2) ⇒ (100-y-z)+20y+100z=2000 ----------------------from eqn(1) ⇒ 99z+19y=1900 ⇒ 80z+19z+19y=1900 ⇒ 80z+19(y+z)=1900 ⇒ 80z+19(100-x)=1900 ⇒ 80z-19x=0 x/z=80/19 therefore when x=80,then z=19 ⇒ when x is less than 80 then z will be in fraction which is not possible ⇒x≠80 since because x,y,z can take only numeric values therefore x =80 ,z=19,y=1
