sanilbabu  (9 years ago)

here not mentioned working hours of 64 people
so take it is as 8hours
let us m=man, h=hours, w=amount of work,d=no of days
use formula as
(m1*d1*h1)/w1 =(m2*d2*h2)/w2
i.e (16*12*8)/52=(64*d2*8)/206
then d2= 309/26
d2= 11 days 7hr approximately

raja babu singh  (9 years ago) Best Solution

work per day epr hour per person= 52/(12*8*16) // eq-1

people= 64; let suppose day=p; per day work for 8 hours
acc. to condition
work per day epr hour per person= 206/(p*8*64) // eq-2

eq-1==eq-2;
p= 309/26

archit garg  (9 years ago)

step 1:
we have to find the days so:
12*
step2:
we have more people than less working days will be required to write the books numerator should be less so:
12*16/64*
Step 3:
now we have more books so more working days will be required to write the books so numerator should be more so:
12*(16/64)*(206/52)= 309/26= 11 days + 23 hrs
now we have 8 hrs per day so 23 hrs = 2 days +7 hrs
so solution is 13 days and 7 hrs..

(96*16*206)/(52*64)=95.07
IF THEY WORKING 8 HOUR PER DAY SO 95.07/8=11.88 OR 12 DAY REQUIRE.
