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?

How Many more lites of water are needed to fill both tanks to their brim?

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.
