What percent of time did Nik spend with clients on Thursday?
a. 10%
b. 70%
c. 30 %
d. 80%

Answer 1

Answer: b. 70%

Step-by-step explanation:

Given : Nik logs the following hours meeting with clients (c) or doing other work (o) :

Mon: 6 c, 4 o

Tue: 8 c, 2 o

Wed: 9 c, 1 o

Thu: 7 c, 3 o

Fri: Off

The number of hours Nik spend with clients on Thursday = 7 [Number of corresponding to c is 7 in the table]

Total hours he spend in work on Thursday =  7+3 = 10

The percent of time Nik spent with clients on Thursday :

$\dfrac{\text{Number of hours he spent with clients}}{\text{Total works he work on Thursday}}\times100\\\\=\dfrac{7}{10}\times100=7\times10\%=70\%$

Hence, the Nik spent 70% of his time with clients on Thursday.

Thus , the correct option is b. 70%.
