Question
In the mixture of 84 liters, the ratio of milk and water
is 3 : 4. If this ratio is changed to 3 : 5, then tell the amount of excess water (in liters) mixed in the mixture.Solution
Total quantity of mixture = 84 liters Quantity of milk in the mixture = 3/7 x 84 = 36 liters Quantity of water in the mixture = 84-36 = 48 liters Let the quantity of water added to the mixture be x liters. 36/(48 + x) = 3/5 36 x 5 = (48 + x) x 3 180=144 + 3x 3x = 180-144 3x = 36 Â x = 36/3 x = 12 liters.
Given a triangle with two sides measuring 12 cm and 16 cm, which of the following cannot be a possible length for the third side?
- Find the remainder on dividing (5x 3  + 4x 2  – 10x + 1) by (2x – 4).
The area (in sq, units) of the triangle formed by the graphs of 8x + 3y = 24, 2x+8 = y and the x – axis is:
If x −y =4and xy =45,thenthevalueof x 3 −y3is:
If x + y = 2 and 1/x + 1/y = 18/15, then find the value of (x3 + y3)?
22% of ‘x’ is equal to 66% of ‘y’, then find the value of x: y.
If y + 1/y = 2 then find y117 + 1/(y117)
if a2 + b2 + c2Â =Â 2(4a -5b -9c)-122 , then a-b-c = ?
If a – b – c = 0, then the value of (a2 + b2 + c2)/(b + ac) is:
If 5x - 13xy + 6y = 0, find x : y.
