Sold 1/6 of the remainder and 250 left.
So 5/6 left = 250
So remainder is 6/5 × 250 = 300
Sold 2/5 to get 300 left.
So 3/5 left = 300
So started with 5/3×300
= 500

250 ÷ [(1 - 1/6) × (1 - 2/5)] = 500

Hi Raymond... Is this correct or its a fluke.. Ans is Same
(250x6/5)x5/3= 500

Correct. Same idea as mine.
Mine would simplify to
250 ÷ (5/6 × 3/5)
= 250 × 6/5 × 5/3
= 500

1-1/6=5/6
1-2/5=3/5
5/6×3/5=1/2
1/2=250
2/2=500

Because both tanks had equal amounts of water (2.4 litres each) at the end, 'return' the 1.35 litres from B to A.
So, 2.4 litres - 1.35 litres = 1.05 litres

Hi, Elaine. Refer to the image for an explanation. Properties of angles in a triangle are involved. :)

Angle y = angle CBD + 35 (ext. Angle = sum of 2 into. opposite angles)
Angle x + angle CBD = 180 (angles on a straight line)
Angle x + angle y = 180 + 35 =215
