Fill The Tank Riddle

3rd and 4th.Let us break down the problem into 5 steps.1. The water in tank1 will get filled up to the connectivity of tank1 and the tank2 and then it will start flowing to tank2.2. The water in tank2 will get filled up to the connectivity of tank2 and the -tank3 and then it will start flowing to tank3.3. The water in tank3 will get filled up to the connectivity of tank2 and the tank3 and then it will start flowing to tank3.4.

#2 - Sachin Ramesh Tendulkar Eqaution Puzzle

If,

Sachin + Ramesh + Tendulkar = 6

Sachin x Ramesh = 2

Ramesh x Tendulkar = 6

Then,

Tendulkar x Sachin =?

3

Sachin + Ramesh + Tendulkar = 6
Sachin x Ramesh = 2
Ramesh x Tendulkar = 6

Given.
Sachin x Ramesh = 2
Ramesh x Tendulkar = 6

Rewriting Both equations in terms of Ramesh,
Sachin = 2/Ramesh
Tendulkar = 6/Ramesh

Replacing above values in equation "Sachin + Ramesh + Tendulkar = 6"
2/Ramesh + Ramesh + 6/Ramesh =6
(2 + Ramesh^2 + 6)/Ramesh = 6
8 + Ramesh^2 = 6Ramesh
Ramesh^2 - 6Ramesh + 8 = 0
(Ramesh - 4) (Ramesh - 2) = 0

Therefore;
Ramesh = 4 or 2

Let us take value of Ramesh as 2
Sachin = 2/2 = 1
Tendulkar = 6/2 = 3

Therefore;
Tendulkar x Sachin = 3 x 1 = 3
