Simplest way to do this:
number of books= 120
percentage represented by 120= 100%
increase current percent by 55%= 155%
: . 55% increase = original number of books * (155%)
= 120 * (155/100)
= 186
Answer:
B. 2
Step-by-step explanation:
We have been given that a worker carries jugs of liquid soap from a production line to a packing area, carrying 4 jugs per trip.
Since worker has made 17 trips, so total number of hugs of liquid soap would be 17 times number of jugs carried per trip.
.
Since each carton holds 7 jugs, so number of cartoons would be
.

We can see that there are 9 completely filled cartoons and there are 5 jugs remaining, so we need
jugs.
Therefore, we need 2 jugs to fill the 10th cartoon and option B is the correct choice.
