Mr Muthu bought a refrigerator worth $1450 with his monthly salary. After spending 1/6 of his remaining salary on a digital camera, he had 5/8 of his salary left. What was Mr Muthu's salary?

Salary = s

(s-1450)5/6 = 5s/8

8s - 1450x8 = 6s

s = 5800

8s - 1450x8 = 6s

Thank you for working out the answer. Can work out without using equation?

Hi 2DMommy


I do not know how to post the model here but I hope you can understand my working.

5/8 of his salary left --- there is a total of 8 units for his salary
after he bought the refrigerator $1450
1/6 of remaining salary on digital camera, so left 5/6 of remaining salary
5/6 of remaining salary is equal to 5/8 of salary
so that means he spend 1/8 of salary on digital
so 2/8 of salary ---- $1450
1/8 of salary ----$1450/2 = $725
Muthu's salary ---- $725 x 8 = $5800

Hi liketoeat

3 x 2 x 3 = 18 ways

You can also list out and do different combinations you will also get 18.

The length of a rectangle is thrice its breadth. If the lenth of of the rectangle is x cm, find the perimeter of the rectangle.(leave your answer in terms of x)


is this way excepted?

1 rectangle ---------> 2x + 2/3 x

3 rectangle----------> 6x+ 6/3 x = 8x


8x/3 ( 1 rectangle)


is this accepted instead of 2+2/3 x?

thanks

Hi beauty queen

I have raised this question in this forum before and confirm with the school maths teacher. Yes, you have to simplify 2x +2/3x to 2 2/3 x or 8/3 x.
