im only in 7th grade so im not sure about the 2nd two, but i believe the first one is 10%
----> x over 100% equals 5 over 49.95 (49.95-44.95=5) then cross multiply 5 and 100 to get 500 and then divide by 49.95 and you get 10.01 001 reapeating

1 , sales P= LIST P * ( 1+/-profit/discount /100) *100
=44,95= 49.95( 1-D/100)*100 GIVES D=10%. so ans =B
2 let original l=1 , so new lenth =2 hence
new .volume = newL cube=(2) cube=8 times so ans =A
3. = (2000 / 1000) / (2/60) =60 km/hr. , SO ANS = B
