There is 20 L * .24 = 4.8 L of acid
8% solution using 4.8 L of acid must have a a total volume of 4.8 * 100 / 8 = 60 L
Add 40 L of water to bring total volume of solution to 60 L

permit x = no. of ltrs of water to characteristic to 24 l of 20 % answer to make an 8 % answer 24/one hundred × 20 = 8/one hundred(x + 24) 24 × 20 = 8(x + 24) 480 = 8x + 192 480 – 192 = 8x 288 = 8x x = 288/8 = 36 ltrs of water to characteristic

Just take the ratio 24%/8% = 3. Now mulitply 20L by 3 gives 60L. So you need to add 60L - 20L = 40L
