p can do a work 3 times faster than q and therefore takes 40 days less than q. find the time in which p and q can complete the work individually. |
|
Answer» Let the no. of days taken by ‘p’ to complete the work is DENOTED by D P works 3 times faster than Q. Therefore, no. of days taken by q = 3D Since p completes the work in 40 days LESSER than q, D = 3D-40 = > 2D= 40 D = 20 So, p takes 20 days to complete Q takes 20 x 3 = 60 days to complete the same work Combined work of p and q can be calculated by taking L.C.M 20 x 60 / (20 + 60) = 15 So, p and q together will take 15 days to complete the work |
