Answer 2

Answer:  1) 12000 cups can be distributed to the victims.

2) The total cost to the trust is rs 97,920.

Step-by-step explanation:

Since,

$\text{ The total numbers of cup}=\frac{\text{ Total quantity hold by cups}}{\text{ Total volume of one cup}}$

Here, the cup is of conical shapes which having radius 7 cm and height 12 cm,

⇒ The volume of one cup = 1/3 × (7)² × 12 = 616 cm³

And, the total quantity hold by cups = 7392 liters = 7392000 cm³,

( 1 liters = 1000 cm³ )

Hence, the total numbers of cup = $\frac{7392000}{616}$

= 12000

Now, the cost of one conical cup is rs 2 and cost of milk is rs 10 per litre estimate the total cost to the trust.

Thus, the total cost to the trust = 2 × Number of cups + 10 × total quantity distributed( In liters)

= 2 × 12000 + 10 × 7392

= 24000  + 73920

= 97,920  rupees
