Question
36 liters of milk were kept in a container. 1.8 liters
were removed and replaced with water. This procedure was performed one more time. How much milk does the container now hold?Solution
we know. remaining milk in the container = Original amount × [1- amount taken out /original amount] ⁿ = 36[1-1.8/36] ² =36[1-1/20] ² = 36[19/20] ² =36×361/400 =361×9/100 =3249/100=32.49
(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
15% of 1800 + 22 = ?
