45 × 1125 100 Let x lt of the water be added to it to obtain a solution between 25% and 30% solution
13.The amount of acid in 1125lt of the 45% solution= 45% of 1125=
⇒ 2025 > (1125 +x ) > 1687.5 ⇒ 2025 − 1125 > x > 1687.5 − 1125 ⇒ 900 > x > 562.5 ⇒ 562.5 < x < 900 ⇒ Between 562.5 and 900 lt of water needs to be added.
