Question

ratio of the number of a lemon to the number of glass of water in the bottle of lemon juice is 2.5 how much glass of water will be mix with 12 11​

Answer 1

Answer:

Ratio of Lemon to water=3:5

Number of lemons =12

3 parts of lemon =12

∴1 part of lemon ≡

3

12

=4

∴5 part of water ≡4×5=20

∴ number of cups of water to be used=20

Answer 2

Appropriate Question :

›»› Ratio of the number of a lemon to the number of glass of water in the bottle of lemon juice is 2:5 how much glass of water will be mix with 12.

Answer :

›»› 20 glass of of water will be mix with 12 lemons.

Given :

• Ratio of the number of a lemon to the number of glass of water in the bottle of lemon juice is 2:5.

To Find :

• How much glass of water will be mix with 12.

Solution :

→ Lemon = 12

→ Lemon : Water = 2 : 5

→ Lemon/Water = 2/5

Let us assume that, the "x" galas of water will be mix with 12.

→ 12/Water = 2/5

We can write,

→ 12/x = 2/5

Cross multiply,

→ 12 * 5 = 2 * x

Multiply 12 and 5,

→ 60 = 2 * x

Multiply 2 and x,

→ 60 = 2x

Move the variable to left-hand side and change the symbol,

→ 60 - 2x = 0

Move the constant to right side and change the sign,

→ -2x = -60

Change the sign of both sides of the equation,

→ 2x = 60

Divide both sides by the same number,

→ x = 30

Hence, 20 glass of of water will be mix with 12 lemons.

Verification :

→ 12/Water = 2/5

→ 12/30 = 2/5

→ 6/15 = 2/5

→ 2/5 = 3/5

→ 2 * 5 = 2 * 5

→ 10 = 10

Here, LHS = RHS

Hence Verified !
