Hard ratio question.
MrRa [10]

The amount he should sell for one bottle of the fizzy juice to make the 60% profit is 22 Penny.

<h3>Cost of each juice</h3>

Orange :  Lemonade

  3  :  5

After buying 2 liters of orange juice and 3 liters of lemonade, cost of each;

Increase the ratio to form divisible by 2 and 3; (L.C.M of 2 and 3 = 6)

(3 x 6L)  :  (5 x 6L)

18L  :  30L      

total fizzy juice = 18L + 30L = 48 liters

bottle of orange = (18 L ÷ 2 L) = 9 bottles

bottle of lemonade = (30 L ÷ 3L ) = 10 bottles

cost of orange = 9 x £1.20 = £10.8

cost of lemonade = 10 x £1.50 = £150

Total cost = £10.8 +  £150 =  £25.80 =  2580 P

<h3>Total bottles that will make 48 liters fizzy juice</h3>

250 mL = 0.25 L

0.25L(n) = 48 L

n = 48/0.25

n = 192 bottles

<h3>Cost of each bottle in Penny</h3>

cost = 2580 P/192

cost = 13.44 P

<h3>Amount each bottle should be sold to make a profit of 60%</h3>

A = 100%(initial cost) + 60%(initial cost)

A = 160%(initial cost)

A = 1.6(initial cost)

A = 1.6 x 13.44 P

A = 21.5 P ≈ 22 P
