Answer:

The answer is 160 kg.

Step-by-step explanation:

Hi here is the step-by-step explanation :-

Let the sweet worth 110 rupees = x

Cost of the sweet worth 110 rupees = 110 x

Cost of the sweets worth rupees 80 per kg = 80 × 30 = 2,400

So, lets say 110 x + 2,400 = 100( x + 80)

= 110 x + 2,400 = 100 x + 800 (Using distributive property)

= 110 x - 100 x = +800 - 2,400 (We have transposed the values, and the symbols change while transposing from LHS to RHS or RHS to LHS)

= 10 x = 1,600 (We subtracted the values)

= x = 1,600/ 10 (We transposed the 10 to the LHS, so it will divide with 1,600)

= x = 160  

Therefore, 160 kg worth of sweets should be mixed with sweets worth 80 per kg to form a mixture of 100 per kg.

Answer:

60 kg of ₹110 per kg

Step-by-step explanation:

sweet of 40 kg cost rupees 80 perkg

sweet of x kg cost rupees 110 per kg

from mixture of cost =₹100/kg

let,

x kg=amount of sweet is ₹100/kg(per kg)

:. total cost of sweet equals to

total cost of 30 kg swset=80×30

=2400

mixture weight = x+30

:. total cost of both sweets=total cost of mixture

110x+2400 = (x+30)100

110x+2400 =100x+3000

110x-100x =3000-2400

10x =600

x =600/10

x = 60

:. 60 kg of ₹110 per kg.
