1
If the toll is to be collected through and outsourced agency by allowing a maximum 10% commission how much amount should be permitted to be collected by the outsourced agency, so that the project is supported with Rs. 4,910 crores?
Discuss
Answer & Solution
Let the amount permitted to be collected = Rs. x
$$\eqalign{ & x = 4910 \times \left( 1 + \frac{10}{100} \right) \cr & x = \left( 4910 \times \frac{110}{100} \right) \cr & x = 491 \times 11 \cr & x = \text{Rs. }5401 \text{ crores} \cr} $$

Discuss
Answer & Solution
Total funds
= 29952 + 11486 + 5252 + 4910 + 6000
= 57600
57600 = 360°
then,
29952 = $$ \frac{29952}{57600} \times 100 $$
            = 52°
3

Discuss
Answer & Solution
The amount require for compensation
= 11486 - 9695
