Answer:
Step-by-step explanation:
Answer:
75%=x-125
90%=x+250
subtract the second from the first
15%=375
100%=?
100%×375/15
100%=2500marked price is 2500
2500+250=2750
90%=2750
100%=?
cost price=3055.56
Answer:
one is equal
Step-by-step explanation:
this is asking which 2 paired items have the same fractional ratio I believe. So all we have to do is make ratios of price to item amount and see if they are equal.
1. 4.5/3 = 6/5
this one we divide numerator and denominator of left side by 1.5 and get:
3/2 = 6/5
this is not true so wrong
2. 5/2 = 15.25/6
2.5 = 2.5416666
sometimes easier to use calculator then reduce. But not equal so wrong.
3. 4.75/5 = 9/10
95/100 = 9/10
wrong
4. 9/4 = 13.5/ 6
4.5/2 =4.5/2
this one is equal
