1. original amounst
A = x, B = 2x, C = 3x
After the death,
A has x + (1/4)(3x) = 7x/4
B has 2x + (3/4)(3x) = 17x/4
B-A = 2000
17x/4 - 7x/4 = 2000
17x - 7x = 8000
10x = 8000
x = 800
take it from there
2. Start with the smallest rectangle
small-width = x
small-length = 4x
large-width = 3x
large-length = 12x
large per = 30x
small per = 10x
Can you finish it?
3. let the length of the journey be 2x
so x/100 + x/60 = 40/60
its all yours .....
I'm really struggling with word problems right now. Got through 20 just three left. Can someone please give me some pointers or the first few steps?
1. A sum of money is divided between A, B and C in the ratio 1 : 2 : 3. However, before the
money is divided C dies and it is decided to divide his share between A and B in the
ratio 1 : 3. If After C’s share is divided B has $2000 more than A, how much money was
there altogether?
2. Rectangles A and B are both four times as long as they are wide and the length of
rectangle A is three times the length of rectangle B. If the difference in the perimeters
is 16 cm, find the dimensions of each rectangle.
3. A certain journey took 40 min to complete.
If half the distance was travelled at an average
speed of 100 km/h and the other half at an
average speed of 60 km/h, what was the
length of the journey?
