Question
Anmol can complete a piece of work in 25 days. Together
with Garima he can complete the same work in 15 days, while Anmol and Aseema working together can complete the same work in 20 days. In how many days can Garima and Aseema working together complete the same work?Solution
According to the question, Work done by Anmol in one day = 1/25 Work done by Anmol and Garima in one day = 1/15 Work done by Anmol and Aseema in one day = 1/20 Work done by Garima in one day = (Work done by Anmol and Garima in one day) - (Work done by Anmol in one day) 1/15-1/25 = (5-3)/75 = 2/75 Work done by Aseema in one day = (Work done by Anmol and Aseema in one day) - (Work done by Anmol in one day) 1/20 -1/25 = (5-4)/100 = 1/100 Work done by Garima and Aseema in one day = (Work done by Garima in one day) + (Work done by Aseema in one day) 2/75 + 1/100 = (8 + 3)/300 = 11/300
