Question
In container P, there is 110 litres of milk and in
container Q there is 70 litres of water. 30% of milk and 50% of water is taken out from the respective containers and are mixed in container R. How much water should be added to container R such that the ratio of milk to water becomes 3:4? MTSolution
Quantity of milk in container R = 0.30 × 110 = 33 litres Quantity of water in container R = 0.50 × 70 = 35 litres Let x litres of water is added to the container R. According to the question, 33/(35 + x) = 3/4 Or, 132 = 105 + 3x Or, 3x = 27 Or, x = 9 Therefore, water added to container R = 9 litres
What value should come in place of the question mark (?) in the following question?
2000 ÷ 10 + 250 × 2 �...
1120 / √x = 80 Then x = ?
- What will come in place of (?), in the given expression.
144 ÷ √36 + 13² – 100 = ? Find the simplified value of the given expression:
(12 ÷ 3 of 2 + 11 of 2) ÷ 4
25% of 300 + √(?) = 35% of 600 - 15% of 300
45% of 1020 + ?% of 960 = 747
- What will come in the place of question mark (?) in the given expression?
121/? = ?/144 6% of 520 + 5% of 620 = ?
