Question
A can initially contains a mixture of glycerine and
water, with 60 liters more glycerine than water. When 20% of this mixture is removed and replaced with 16 liters of glycerine and 64 liters of water, the quantities of glycerine and water in the can become equal. Determine the initial quantity of water in the can.Solution
Let initial quantity of water in the mixture be ‘x’ litresTherefore, initial quantity of glycerine = (x + 60) litresFinal quantity of glycerine in can ‘A’ = {0.8(x + 60) + 16} = (0.8x + 64) litresFinal quantity of water in can ‘A’ = (0.8x + 64) litresTherefore, initial quantity of glycerine cannot be determinedHence, option e.
Simplify:
6x + 8y - [(12x + 6y) - (4x + 3y) + 2y] - 4xIf 9x2 + 16y2 = 24xy, then find the ratio of ‘x’ and ‘y’, respectively.
- Suppose [a + (1/16a)] = 3, then the value of [16a³ + (1/256a³)] is:
If, 6x + y = 20, and 2xy = 32, and 6x > y, then find the value of 216x³ – y³.
If x + 1/x = 2, find x⁷ + 1/x⁷.
(x – 6) 2 + (y + 2) 2 + (z – 4) 2 = 0, then find the value of 4x - 3y + z.
