(b) 5.5%

Answer 1

1. 3: will get 84
4: will get 112
5: will get 140

2. I don't know

Answer 2

(1)

Let the common ratio be x.

A : B : C = 3x : 4x : 5x.

Given that sum of money = 336.

= > 3x + 4x + 5x = 336

= > 12x = 336

= > x = 28.

Therefore:

Share of A = 3 * 28

= 84.

Share of B = 4 * 28

= 112

Share of C = 5 * 28

= 140.

(2)

(a) 25%

= > 25/100

= > 1/4

= > 1 : 4

(b)

Given decimal is : 5.5%

= > 55/10

= > 55/10 * (1/100)

= > 55/1000

= > 11/200

= > 11 : 200.

Hope this helps!
