Salary = s

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

8s - 1450x8 = 6s

s = 5800

8s - 1450x8 = 6s

s = 5800

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
