Question
A vessel contains some milk .6 liter of the milk was
taken out of the vessel and replaced with 6 liter of water and again 6 liter of mixture was taken out and was replaced with water. Now the ratio of milk to water become 100:96. Find the initial Quantity of milk in the vessel.Solution
Let the Quantity of milk initially is x liter. Using Direct Formula, =100/100+96 = (x-6 / x)2 =100/196 = (x-6/x)2 x-6/x = 10/14 14x -84 = 10x 4x = 84 X =21 liter

Evaluate: 320 − {18 + 4 × (21 − 9)}
Simplify: 72 ÷ 6 × 3 − 8 + 4
118 × 6 + 13 + 83 = ?
Simplify the following expression:
  (400 +175) ² - (400 – 175) ² / (400 × 175)
150% of 850 ÷ 25 – 25 = ?% of (39312 ÷ 1512)
(75 + 0.25 × 10) × 4 = ?2 - 14
26% of 650 + 15% of 660 – 26% of 450 = ?
115% of 40 + 3 × 4 = ? × 11 – 8
