9. The cost of a frock at a shop was Rs 450. The sales tax charged was 5%. Find the bill amount?
10. A skirt bought for Rs 250 and sold at Rs 150. Find the loss per cent?

ANSWERS:

1. 1:4
2. Discount
3. 16
4. Sales tax
5. Interest
6. First find out the 15% of 24000 = 15 x 24000/100 = 3600
   New price = Old price + Increase = 24000 + 3600 = 27600
7. Sum of the parts = 2 + 3 + 5 = 10
   2/10 x 100% = 20%
   3/10 x 100% = 30%
   5/10 x 100% = 50%
8. Here we can find out 36% of 25 = 36 x 25/100 = 9 students
9. Original price (CP) = Rs 450
   Sales tax in rupees = 5% of its CP = 5 x 450/100 = 22.5
   Bill amount = CP + Sales tax = 450 + 22.5 = 472.5
10. Here CP = 250, SP = 150
    Since CP> SP, then there is a loss = 250 -150 = 100 rupees
    Loss per cent = Loss x 100/CP = 100 x 100/250 = 40%.
