Ans : C
Let their shares be x and (5000 - x)

= 7 : 3
Ans : A
Each interval is of length 2p
Let any point in the sixth interval be x.
10p
< x < 12p

Of the choices given, only 23p/2 fits the above condition.
Ans : C
- Formula:
Total worth in cents =
10 cents x z coins + 5 cents x
(z - 3 coins)
coin coin
Total worth of coins = 10z + 5 (z - 3)
=
10z + 5z - 15
=
15z - 15
=
15 (z - 1)
Ans : C
