darlenese:40 boys cleared it in 6 days 30 boys will be? 40/30 X 6 = 4/3 X 6 24/3 = 8 days. The secret is : 40 did it in 6 days, that means it will take more time for 30 men to do it. More reason why it becomes 40/30 so that the days would be increased. Let me give you another example. If 3 boys can fill a tank in 18 minutes. In how many minutes can 6 boys do it? If you observe, 3 boys can do it in 18 minutes, that means 6 boys will do it in less than 18 minutes. For it to be less, 3/6 (boys) X 18 = 9 minutes. If I want to find in how many minutes 2 boys will do it, it means that it must be greater than the time 3 boys did it or will do it. Which will be 3/2 x 18 = 27 minutes. If you don't understand, you can email me your contact and I will explain on whatsapp or any medium. |

It will always take 40 boys to work per day in 1farm 40boys * 6days= 240 appearances for job to be done 30 boys*6days= 180 appearances for 30 boys in 6days 240 - 180 = 60 (60 appearances missing in 6days) and the 30 men need to meet up If every 40 appearances= 1day Then 60 appearances= 1.5days. i.e 60/40 So the 30 boys will work extra 1.5 days out of 6days (6+1.5) = 7.5 days It will take 7 days 12 hours for 30 men to work in the farm I hope it makes sense |
