In an alloy of three metals, ratio of the quantity of gold, silver and platinum is 5:6:4, respectively. If total quantity of silver and platinum together is 270 kg then find the difference between the quantity of silver and gold.
Let the quantity of gold, silver and platinum be ‘5x’ kg, ‘6x’ kg and ‘4x’ kg, respectively. Total quantity of silver and platinum together = 270 kg 6x + 4x = 270 Or, x = 27 Difference between the quantity of silver and gold = {(6 – 5) × 27} = 27 kg
600.11 ÷ 14.98 x 5.14 – 171.9 = √?
24.99% of 1619.78 + (1259.84 ÷ 12.24) = ? × 16.98
Direction: Solve the following expression and calculate the approximate value.
398% of 388 + 129% of 323.89 – 430.93
21.11 × 4.98 + 22.03 × 4.12 – 31.95 + 95.9 × 3.02 =?
416.021÷ 3.782 + 13.012× 24.987 =?
...16.22 × 12.99 + 142.15 = ?
? = 54.89 × 270.08 ÷ 135.17 + 464.35 ÷ 29.03
14.12 × 21.98 + 25.22% of 195.99 = ? × 50.9
(2744)1/3 × 10.11 × 5.97 ÷ 14.32 = ?+ 15.022
80.08% of 1250.25 + 64.02% of 1200 = 24.02 × 36.025 + ?% of 2259.98
