Qn 18) Tanks X and Y are each filled with some water. If water from Tank Y is poured into Tank X until the water in Tank X reaches the brim, there will be 8 litres of water left in Tank Y. If water from Tank X is poured into Tank Yuntil the water in Tank Y reaches the brim, there will be 26 lites of water left in Tank X. The ratio of the volume of Tank X to the volume of Tank Y is 5:3. How Many more lites of water are needed to fill both tanks to their brim?


Many thanks in advance!!

Vol of X: Vol of Y
= 5u : 3u

Water from Y poured into X====5u + 8
water from X poured into Y=====3u + 26

Thus, 5u + 8 = 3u + 26
2u = 18
1u = 9

Vol of water in both tanks now= 9 x 5 +8 = 53
Vol of both tanks = 9 x 8 = 72
Diff = 72 - 53 = 19

Ans: 19 litres more

Hi,
I think it's not necessary to draw model in this case. Thanks.
