Quantitative Comparison A if the quantity in Column A is greater B if the quantity in Column B is greater C if the two quantities are equal D if the relationship cannot be determined from the information given

Solution

17)column A=x+(75/100x)=1.75x

column B=1.75x

1.75x>0.75x

A.quantity in column A is greater

18)relationship cannot be determined as number of boys and number of girtls are not given

19)let principle amount to be invested =p

t =5 , i =1440 , r =7.2%=0.072

i =pr t

1440=p*0.072*5

p=1440/(0.072*5)

p=4000$

amount to be invested =4000$

20) let number be x

x*150/100 = 72

x =72*100/150

x =48

number =48
