###### Formulae

1. Gain = (S.P.) - (C.P.)

2. Loss = (C.P.) - (S.P.)

3. Loss or gain is always reckoned on C.P.

4. Gain Percentage = Gain x 100/C.P

5. Loss Percentage = Loss x 100/C.P

6. Selling Price = (100 + Gain %)x C.P/100

7. Selling Price = (100 - Loss %)x C.P/100

8. Cost Price = 100x S.P/(100 + Gain %)

9. Cost Price = 100x S.P/(100 - Loss %)

⇒x=80/5

=16

Question 4

A profit of Rs.19488/- is distributed amongst three partners X, Y and Z in the ratio of 5 :2: 7 respectively. What is the total of Y's and Z's share?
