Question
750 ml mixture contains milk and water in the ratio of
11:14 respectively. If 30% of the mixture is taken out, and 180 ml of water is added into the remaining mixture, then the ratio of milk to water in resulting mixture will be:Solution
ATQ,,
Initial mixture: 750 ml, with milk ratio = 11:14 Milk = 330 ml, Water = 420 ml 30% of mixture removed: 225 ml (99 ml milk, 126 ml water) Remaining: 231 ml milk, 294 ml water Add 180 ml water: New water = 294 + 180 = 474 ml New ratio: 231 ml milk : 474 ml water = 77:158
(22 × 52 ) + 4 × 6 = ? - √324
What should come in place of (?) question mark in the given expression.
 (25% of 320) + (3/8 of 400) − 30 = ?
(5832)1/3  × 10.11 × 11.97 ÷ 16.32 = ? + 45.022
82% of 400 + √(?) = 130% of 600 - 85% of 400
If (x + 1/x) = 5, then value of x3 + 1/x3 is:
Simplify: (1 ÷ 0.08)
What should come in place of (?) question mark in the given expression.
{ (144 ÷ 12) × 5 } − (18 ÷ 3) = ?
Simplify the following expressions and choose the correct option.
(3/4 of 256) + (2/5 of 150) - (72 ÷ 7)
464 + 181 +? = (154 × 25) - (15) 2 Â
15% of 1800 + 22 = ?Â
