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
What will come in the place of question mark (?) in the given expression?
(63 - ?) ÷ 5 + √625 = 19 X (9 - 6)
- What will come in place of (?), in the given expression.
(4² + 6²) × 2 = ? What will come in the place of question mark (?) in the given expression?
(40/25) X 80 - ? = 45% of 300 - 5525.6% of 250 + √? = 119
1220 ÷ 61 ÷ 5 + 450 of 20% - 70 = √ ?
Simplify the expression:
(5x + 15) / (x² + 3x)
What will come in the place of question mark (?) in the given expression?Â
435 ÷ 29 X 792 ÷ 44 = √(? + 14) + 35 + 221 ÷ 17
...192.251 + 326.233 + 125.021 + 19.273 = ?
36% of 640 – 12.5% of 352 + 25% of 640 = ? – 48% of 432
Simplify the following expressions and choose the correct option.
18 * 15 - {3/5 of 250 + 72}
