Rajeev buys good worth Rs. 6650. He gets a rebate of 6% on it. After getting the rebate, he pays sales tax @ 10%. Find the amount he will have to pay for the goods.
Answer: Option
Explanation:
| Rebate = 6% of Rs. 6650 = Rs. |  |
6 | x 6650 |  |
= Rs. 399. |
| 100 |
| Sales tax = 10% of Rs. (6650 - 399) = Rs. | |
10 | x 6251 | |
= Rs. 625.10 |
| 100 |
Final amount = Rs. (6251 + 625.10) = Rs. 6876.10

@Dezal.
Out of 20 liters, 20% is water and remaining 80% is milk. In the second case, the volume is increased by adding water only. So milk % will remain same(80%).

Let make marks be = x.
40% of x = 40 + 40.
40/100(x) = 80.
x = 200.
Hope this will help you.

Total price = 6650.
This is common for both tax and rebate.
Rebate = 6% reduce the Total price then.
Tax = 10% increase the Total price.
So we take (10%-6%) = 4%, (4/100)*6650+6650 = 6676.10.

A = 150% of B = 150/100*B = 3/2B.
C = 120% of A = 120/100*A = 6/5A = 6/5*3/2B = 9/5B.
A+B+C = 86000.
3/2B+B+9/5B = 86000.
43B/10 = 86000.
So B = 20000.
3/2*20000+20000+C = 86000.
C = 86000-50000 = 36000 OR C = 9/5*20000 = 36000.
C = 120% of A = 120/100*A = 6/5A = 6/5*3/2B = 9/5B.
A+B+C = 86000.
3/2B+B+9/5B = 86000.
43B/10 = 86000.
So B = 20000.
3/2*20000+20000+C = 86000.
C = 86000-50000 = 36000 OR C = 9/5*20000 = 36000.
