Question

Twenty caravans are travelling across the desert one day apart. The first carvan reached the oasis and the camels drank half of the water in the pool. On the second day, the second carvan reached the oasis and the camels drank one-third of the water that was left. On the third day, the camels in the third carvan drank one- quarter of the water that was left. On the first day the pool contained 1050m' of water. How much water was left after the 20th carvan passed through​

Answer 1

Answer:

50m

Step-by-step explanation:

The first caravan left half of the total water

So, remaining water after first caravan=1/3 of 1/2 of total water

1/3-1/2=1/6

so remaining water left after second caravan =1/2-1/6=1/3

Third caravan water consumed=1/4×1/3=1/12

So, remaining water left after third caravan=n/n+

substitute n =20 water left after 20 caravan =1/20+1=1/21

Thus, the remaining water left 20 caravan=11/21×1050m=50m
