Question
A mixture contains liquid A and liquid B in the ratio of
5:3, respectively. If 12L of liquid B is added to this mixture, the respective ratio of liquid A and liquid B becomes 2:3, what was the quantity of liquid B in the original mixture?Solution
Let, quantity of liquid A and liquid B in the original mixture be ‘5x’ L and ‘3x’ L, respectivelyAccording to question, 5x/(3x + 12) = 2/3 15x = 6x + 24 9x = 24 x = 24/9 The quantity of liquid B in the original mixture = 3x = 24/9 = 8 L
5.5 × 3.2 × 2.3 = ?
What value will come in place of (?) question mark in the given expression.
17 × 15 – 48 ÷ 4 + 9² = ?
Find the value of.
( ∛ ∛ 343 )3 × ( ∛ ∛216 )3
(3984 ÷ 24) x (5862 ÷ 40) = ?
5555 ÷ 11 ÷ 5 = 100 + ?
18 * 9 + 25% of 120 + 50% of 200 = ?
