Let x kg rice is mixed now cost of x kg rice = 110x and cost of 30 kg sweet = 80*30 = 2400 kg ,
Total cost of rice and sweet = 110x + 2400
According to question to produce a mixture for rs 100 per kg
=> ( 110x + 2400 ) / ( x+30) = 100 => 110x + 2400= 100x + 3000 => 10x = 600 = 60 kg answer

Let Wt of sweet mixed =x kg
Total wt of new mixture = x+30
Cost of x kg sweet = 110x Rs
Cost of 30 kg sweet = 80*30 = 2400 Rs ,
ATQ ( 110x + 2400 ) = 100(x+30)
⇒ 110x + 2400 = 100x + 3000
⇒ 10x = 600
⇒ x= 60 kg
60 kg sweet worth 110 must be mixed
Total wt of new mixture = x+30
Cost of x kg sweet = 110x Rs
Cost of 30 kg sweet = 80*30 = 2400 Rs ,
ATQ ( 110x + 2400 ) = 100(x+30)
⇒ 110x + 2400 = 100x + 3000
⇒ 10x = 600
⇒ x= 60 kg
60 kg sweet worth 110 must be mixed
