what I did for 22 is to find a common dominator for 9/25 and 15/23...so i multiplied 25*23....but i think there is an easier way as my way took me long time

Q21 and Q3 have already been discussed.

Q25)
Given, 8% Int of $5000 =$400.
Cross Multiply,
400 = 6.5
?? = 100

=> (400 * 100)/65 = 6154 approx.

Q) The key here is to guess the appoximate values of each factor.
m = 9/25 ~ 10/25 ~ 0.4
w = 15/32 ~ 15/30 ~ 0.5
c = 1 - 0.4 - 0.5 = 0.1 approx

Therefore the order would be
c, m, w.

Hope this helps.

For Q21...

50 mph means you will drive 250 miles in 5 hours.

You get 30 mpg, so 250 miles / 30 mpg gives you 25/3 gallons (8 1/3) you have used.

(25/3) / 12 (total tank) = 25/ 36

Hello MontrealLady, I would suggest you to post all these questions separately on the forum. so that it will be easier for everybody to answer and discuss one question at a time.

For c,m,w q,I did the below way.Instead of calculating the fraction part,better to convert it into decimal.

m = 0.36
w = 0.47
c = 0.2

So the order now becomes

c,m,w

I wud go with option A
