Twenty-four men can complete a work in 16 days. Thirty- two women can complete the same work in twenty-four days. Sixteen men and sixteen women started working and worked for 12 days. How many more men are to be added to complete the remaining work in 2 days?
(A) 16 men (B) 24 men ( C) 36 men (D) 48 me

• 24 men 16 days
  48 women in 16 days(by given data)
  therefore 1 men =2 women
  acc to formulae
  m1*d1=m2*d2
  => 24*16=16*x(x is no of days)
  => 16 men can complete the work in 24 days(x=24)
  16 mens 12 days work=(1/24)*12=1/2
  16 womens 12 days work=1/4(because 1 men=2 women)
  16 days total work by men&women =(1/2)+(1/4)=3/4
  remaining work=1-(3/4)=1/4
  1 man's 2 days work=(1/(16*24))2=1/192
  therefore 1/4 work can be completed by
  2...........1/192
  ?...........1/4
  =24 mens.

• 24 men complete the work in 16 days & 32 women complete the same work in 24 days (given data)
  assume that total work is 1. so 24 man in 16 days complete the total work 1. so 1 man in 16 days done 1/24 and 1 man in 1 day done 1/24*16 and 16 man in 12 days done 16*12/24*16=1/2.. in d same way 16 women in 12 days done 16*12/32*24=1/4.. so 16 man and 16 women in 12 days done (1/2+1/4)=3/4.. remaining work(1-3/4)=1/4.. now 1/24*16 is done in 1 day by 1 men.. so 1/4 in 2 days is done by 24*16/4*2=48 days
