C. 4.
Step-by-step explanation:
The ratio of the lengths of the larger to the smaller is 2:1, because the lengths are doubled.
So the surface area of larger to smaller = 2^2 : 1 = 4 : 1.
1$ = 63.76 rupees (dollar to rupee exchange)
1 rupee = 0.015$ (rupee to dollar exchange)
To buy one dollar, Ria will need 63.76$
Answer: (c)
Now, Ria's annual fees is $42,000. To know how much this is in dollars, use cross multiplication as follows:
tuition fees = (42,000*63.76) / (1) = 2,677,920 rupees
