Answer 2

Step-by-step explanation:

=> A = 6

=> A = 6=> B = 8

=> A = 6=> B = 8 => C = 12

First Lcm of these numbers that is 24

Second Find work for 1 days

=> A = 4

=> B = 3

=> C = 2

B and c work together for 2 days

=> 3 + 2 = 1 day

=> 3 + 2 = 1 day=> 5unit = 1day

=> 3 + 2 = 1 day=> 5unit = 1day=> 10 unit = 2days

=> 3 + 2 = 1 day=> 5unit = 1day=> 10 unit = 2daysSubtract from total work that is 24

=> 3 + 2 = 1 day=> 5unit = 1day=> 10 unit = 2daysSubtract from total work that is 24=> 24 - 10 = 14

=> 3 + 2 = 1 day=> 5unit = 1day=> 10 unit = 2daysSubtract from total work that is 24=> 24 - 10 = 14=> 3 + 2 = 1 day=> 5unit = 1day=> 10 unit = 2daysSubtract from total work that is 24=> 24 - 10 = 14Remaining work = 14

=> 3 + 2 = 1 day=> 5unit = 1day=> 10 unit = 2daysSubtract from total work that is 24=> 24 - 10 = 14=> 3 + 2 = 1 day=> 5unit = 1day=> 10 unit = 2daysSubtract from total work that is 24=> 24 - 10 = 14Remaining work = 14=> 3 + 2 = 1 day=> 5unit = 1day=> 10 unit = 2daysSubtract from total work that is 24=> 24 - 10 = 14Remaining work = 14=> A + B = 1 day

=> 3 + 2 = 1 day=> 5unit = 1day=> 10 unit = 2daysSubtract from total work that is 24=> 24 - 10 = 14=> 3 + 2 = 1 day=> 5unit = 1day=> 10 unit = 2daysSubtract from total work that is 24=> 24 - 10 = 14Remaining work = 14=> 3 + 2 = 1 day=> 5unit = 1day=> 10 unit = 2daysSubtract from total work that is 24=> 24 - 10 = 14Remaining work = 14=> A + B = 1 day=> 3 + 2 = 1 day=> 5unit = 1day=> 10 unit = 2daysSubtract from total work that is 24=> 24 - 10 = 14Remaining work = 14=> A + B = 1 day=> 7 unit = 1day

=> 3 + 2 = 1 day=> 5unit = 1day=> 10 unit = 2daysSubtract from total work that is 24=> 24 - 10 = 14=> 3 + 2 = 1 day=> 5unit = 1day=> 10 unit = 2daysSubtract from total work that is 24=> 24 - 10 = 14Remaining work = 14=> 3 + 2 = 1 day=> 5unit = 1day=> 10 unit = 2daysSubtract from total work that is 24=> 24 - 10 = 14Remaining work = 14=> A + B = 1 day=> 3 + 2 = 1 day=> 5unit = 1day=> 10 unit = 2daysSubtract from total work that is 24=> 24 - 10 = 14Remaining work = 14=> A + B = 1 day=> 7 unit = 1day=> 3 + 2 = 1 day=> 5unit = 1day=> 10 unit = 2daysSubtract from total work that is 24=> 24 - 10 = 14Remaining work = 14=> A + B = 1 day=> 7 unit = 1day=> 14 unit = 2days

=> 3 + 2 = 1 day=> 5unit = 1day=> 10 unit = 2daysSubtract from total work that is 24=> 24 - 10 = 14=> 3 + 2 = 1 day=> 5unit = 1day=> 10 unit = 2daysSubtract from total work that is 24=> 24 - 10 = 14Remaining work = 14=> 3 + 2 = 1 day=> 5unit = 1day=> 10 unit = 2daysSubtract from total work that is 24=> 24 - 10 = 14Remaining work = 14=> A + B = 1 day=> 3 + 2 = 1 day=> 5unit = 1day=> 10 unit = 2daysSubtract from total work that is 24=> 24 - 10 = 14Remaining work = 14=> A + B = 1 day=> 7 unit = 1day=> 3 + 2 = 1 day=> 5unit = 1day=> 10 unit = 2daysSubtract from total work that is 24=> 24 - 10 = 14Remaining work = 14=> A + B = 1 day=> 7 unit = 1day=> 14 unit = 2days=> 3 + 2 = 1 day=> 5unit = 1day=> 10 unit = 2daysSubtract from total work that is 24=> 24 - 10 = 14Remaining work = 14=> A + B = 1 day=> 7 unit = 1day=> 14 unit = 2daysSo,

=> 3 + 2 = 1 day=> 5unit = 1day=> 10 unit = 2daysSubtract from total work that is 24=> 24 - 10 = 14=> 3 + 2 = 1 day=> 5unit = 1day=> 10 unit = 2daysSubtract from total work that is 24=> 24 - 10 = 14Remaining work = 14=> 3 + 2 = 1 day=> 5unit = 1day=> 10 unit = 2daysSubtract from total work that is 24=> 24 - 10 = 14Remaining work = 14=> A + B = 1 day=> 3 + 2 = 1 day=> 5unit = 1day=> 10 unit = 2daysSubtract from total work that is 24=> 24 - 10 = 14Remaining work = 14=> A + B = 1 day=> 7 unit = 1day=> 3 + 2 = 1 day=> 5unit = 1day=> 10 unit = 2daysSubtract from total work that is 24=> 24 - 10 = 14Remaining work = 14=> A + B = 1 day=> 7 unit = 1day=> 14 unit = 2days=> 3 + 2 = 1 day=> 5unit = 1day=> 10 unit = 2daysSubtract from total work that is 24=> 24 - 10 = 14Remaining work = 14=> A + B = 1 day=> 7 unit = 1day=> 14 unit = 2daysSo,=> 3 + 2 = 1 day=> 5unit = 1day=> 10 unit = 2daysSubtract from total work that is 24=> 24 - 10 = 14Remaining work = 14=> A + B = 1 day=> 7 unit = 1day=> 14 unit = 2daysSo,Total days = 4
