Question
Ashish and Anil can do a piece of work in 10 days and 15
days respectively. Ashish completed 40% of the work. Find the time taken by Anil to complete the remaining work.Solution
Let the total work be (LCM of 10 and 15) = 30 units Efficiency of Anil = 30/15 = 2 units/day Remaining work = 30 x 0.6 = 18 units Time taken by Anil to complete the remaining work = 18/2 = 9 days
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.
