Question

3 typist working 8 hours a day type in 10 days . If only 2 typist r working how many hours a day should they work to finish the job in 12 days

Answer 1

Answer:

The number of hours taken by 2 typist to finish job in 12 days is 10 .

Step-by-step explanation:

Given as :

Number of typist = $t_1$ = 3

Number of hours = $h_1$ = 8

Number of days = $d_1$ = 10

Again

Number of typist = $t_2$ = 2

Number of hours = $h_2$

Number of days = $d_2$ = 12

According to question

$t_1\times h_1\times d_1$ = $t_2\times h_2\times d_2$

i.e $3\times 8\times 10$ = $2\times h_2\times 12$

Or, 240 = 24 × $h_2$

Or, $h_2$ = $\dfrac{240}{24}$

∴ $h_2$ = 10 hours

Hence, The number of hours taken by 2 typist to finish job in 12 days is 10 . Answer
