The Answer Would Be 16
How I Found The Answer:
2 x 2 x 2 x 2 = 16
Answer:
Step-by-step explanation:
The numbers in the ratio add up to 10. So divide 250 by 10. One part is £25. Multiply by the given numbers: 3x25=75. 6x25=150. 1x25=25. So you have £75:£150:£25.

Answer:
192.1%
Step-by-step explanation:
The formula for the amount of interest is ...
i = Prt . . . . . where i is the interest amount, P is the principal, r is the annual rate, and t is the number of years. (Here, we have a fraction of a year.)
Solving for the rate, we have ...
r = i/(Pt)
For "exact" interest, we use 365 days in the year. So, for a time of 19 days of 365, the interest rate is ...
r = $35/($350·19/365) ≈ 1.921 = 192.1%
The second one because the answer to the first one is a two digit number and the answer to the second is a one digit number, so #2 only uses two 2-digit numbers
