Write the working equation :

1.) The secretary of the council can draft a communication letter in 15 mins while the assistant secretary can finish the same in 32 minutes.

2.) A number more than 32 divided by 15 more than twice a number is equal to 7/6.

3.) Twice the sum of a number and its reciprocal is same as 33/16?

4.) A certain boat traveled 32 kilometers along with the current and 16 kilometers agains the currents. In the same amount of time, find the rate of the boat if the rate of the current is 2kph.

5.) A student can finish a project 15 minutes earlier than the other student. How long will it take them to finish the project together?

sec = 1/15
asst = 1/32

(32+x)/(2x+15) = 7/6

2(x + 1/x) = 33/16

and so on.

See what you can do with the others here, as well as your two later posts. Do not expect someone here to do your whole assignment. You must be able to make some headway on at least some of them, no?

x= (33±√-3007)/ 64
