Answer 1

Answer:

Step-by-step explanation:

Answer is C

How did we find out?

Well,

We mulitply the first number of each option by 120%, and then we add 600 to the second number. Finally, we calculate their ratio. When we get 3:5 as ratio, we stop the calculation

a)1125 x 120%= 1350 ; 1850 + 600= 2450. Ratio 1350 : 2450 = 27 and 49.

b)1225 x 120%= 1470; 1750 + 600= 2350. Ratio 1470 : 2350 = 147 and 235.

c)1125 x 120%= 1350; 1650 + 600= 2250. Ratio 1350 : 2250 = 3 and 5.

And we have got our answer.
