Answer» If A completes a work in 1 day, B completes the same work in 3 days Hence, if the difference is 2 days, B can complete the work in 3 days => if the difference is 60 days, B can complete the work in 90 days => AMOUNT of work B can do in 1 day= 1/90 Amount of work A can do in 1 day = 3 × (1/90) = 1/30 Amount of work A and B can together do in 1 day = 1/90 + 1/30 = 4/90 = 2/45 => A and B together can do the work in 45/2 days = 221/2 days If A completes a work in 1 day, B completes the same work in 3 days Hence, if the difference is 2 days, B can complete the work in 3 days => if the difference is 60 days, B can complete the work in 90 days => Amount of work B can do in 1 day= 1/90 Amount of work A can do in 1 day = 3 × (1/90) = 1/30 Amount of work A and B can together do in 1 day = 1/90 + 1/30 = 4/90 = 2/45 => A and B together can do the work in 45/2 days = 221/2 days |
