Answer 1

Answer:

600, 780

Step-by-step explanation:

SHORT METHOD

Cp. Mp. Sp

10. 13

4. 3

-------------------------

40. 52. 39

1 => 15

Cp = 40 => 600

Mp = 52 => 780

LONG METHOD

(M.p-C.p)/C.p = 30/100 = 3/10

10M.p = 13C.p or M.p : C.p = 13 : 10. (1)

(M.p-S.p)/M.p = 25/100 = 1/4

3M.p = 4S.p or M.p : S.p = 4 : 3. (2)

Multiply (1) by 4 and (2) by 13

Then M.p : S.p : C.p = 52 : 39 : 40

(Cp - S.p) = 15

40x - 39x = 15

x=15

40x = 600

52x = 780
