Answer 1

Step-by-step explanation:

let acid=2x

let water=9x

a to q

2x+9x=66

11x=66

x=6

acid=2*6

=12 litres

Answer 2

Given:

Acid and water are mixed in ratio 2:9.

To Find:

The quantity of acid in 66 l of dilute acid.

Solution:

Let the acid be 2x

Let the water be 9x

Now,

2x+ 9x = 66

11x = 66

x = 6

Acid = 2 × 6

       = 12 liters.

Therefore, the quantity of acid in 66 liters of dilute acid is 12 liters.
