Question

manjula can complete a stiching job in 4 days and meena can do the same job in 6 days.Both start the work together but manjula leaves the job after 2 days.How much longer will meena take to complete the job?

Answer 1

Meena will take one more day to complete the work.

Answer 2

Meena take the extra 1 day to complete the job.

Step-by-step explanation:

In one day, Manjuba stitching weaves = 1/4

in one day, Meena stitching weaves = 1/6

When manjuba and meena work together =  1/4 + 1/6

                                                                     =  5/12

In one day they stitch = 5/12

So, in 2 days they stitch = 5/12 × 2 = 5/6

Therefore, in 2 days stitching = 5/6

Portion left for stitching = 1-5/6 = 1/6

If meena stitch 1/6 work in one day

So, to stitch 1/6 , she will do = 1/6 × 6/1 = 1 day

Thus, Meena will take one day more to complete the job.
