Question
There is 200 litres of mixture of milk and water in a
jar. The ratio of quantity of milk to water in the jar is 7:5, respectively. If lsquo;xrsquo; litres of mixture is taken out from the jar then the difference between quantity of milk and water left in the jar is 23 litres. Find the value of lsquo;xrsquo;Solution
Let the quantity of milk and water left in the jar be 7a litres and 5a litres, respectively According to the question, 7a ndash; 5a = 23 =gt; a = 11.5 Therefore, quantity of mixture left in the jar = 7a + 5a = 12a = 138 litres Therefore, quantity of mixture taken out = 200 ndash; 138 = 62 litres =gt; x = 62
Evaluate: 360 ÷ [ {18 − (6×2)} × 5 ] + 72 − 33
(43)² - (28)² + (32)² = ?% of 2500
Evaluate:
√729 + √49 - √16 + 1/√64
What will come in place of (?) in the given expression.
12.5 + 7.75 - 3.6 = ?62 of 8 - 320 ÷ 4 = ?3 + 200
2(1/3) + 2(5/6) – 1(1/2) = ? – 6(1/6)
What will come in the place of question mark (?) in the given expression?
30% of 520 + 16% of 1500 = ? + 244
60% of 120 – ?% of 64 = 20% of 200
35% of 840 + 162 = ? – 25% × 300
20% of 240 + 18% of 200 = ?
