400 litres of mixture X contains acetone and glycerine in the ratio 11:14, respectively. 100 litres of the mixture is withdrawn and labelled as mixture Y and 6 litres of acetone is added to it. Find the ratio of glycerine to acetone in mixture Y.
Quantity of acetone in mixture Y = 100 × 11/25 = 44 litres Quantity of glycerine in mixture Y = 100 – 44 = 56 litres After addition of 6 litres of acetone, New ratio of glycerine to acetone = 56:(44 + 6) = 28:25
72% of 486 – 64% of 261 = ?
(6.013 – 20.04) = ? + 9.98% of 5399.98
458.32 - 563.32 + 659.32 =?
193. 69 + 200.09 – 512.96 + 312.09 =?
?% of (√196) × 24 + 344 = 428
(1/8) × (256 × 2)/(8 × 4) + ?3 = 1730
22% of 400 + √ ? = 34% of 800 - 25% of 400
192.251 + 326.233 + 125.021 + 19.273 = ?
