in how many days (D1)?
a) 5 days
b) 4 days
c) 6 days
d) 8 days
Trick:      D/(A1/A + B1/B + C1/C)
               =7/(5/10 + 5/20 + 5/40)
               =7/(1/2 + 1/4 + 2/8)
               =7/{(4+2+1)/8}
               =7/(7/8)
               =(7*8)/7 = 8 days (Ans.)

Que.02) If 1 man or 2 women or 3 boys can do a work in 88 days.
 1 man, 1 woman and 1 boys together will complete the same work
in how many days?
a) 36 days
b) 42 days
c) 48 days
d) 54 days

Trick:      D/(A1/A + B1/B + C1/C)
               =88/(1/1 + 1/2 + 1/3)
               =88/{(6+3+2)/6}
               =88/(11/6)
               =(88*6)/11 = 48 days (Ans.)

Que.03) 3 men or 5 women or 8 boys can finish a work in 38 days.
Then in how many days 6 men and 10 women and 6 boys will complete
this work?

B) 12
C) 9
D) None of these.

Trick:      D/(A1/A + B1/B + C1/C)
               =38/(6/3 + 10/5+ 6/8)
               =38/(2+2+3/4)
               =38/{(8+8+3)/4}
               =38/(19/4)
               =(38*4)/19= 8 days (Ans.)

Que.4) If 2 men or 6 women or 4 boys can finish a work in 99 days.
How many days will one man, one woman and one boy together take
to finish the same work?
A) 44 days
B) 54 days
C) 64 days
D) 104 days
E) None of these.

Trick:      D/(A1/A + B1/B + C1/C)
               =99/(1/2+ 1/6+ 1/4)
               =99/{(6+2+3)/12}
               =99/(11/12)
               =(99*12)/11 = 108
               So, Answer is (E) none of these.

A) 5 * 6/13 months
B) 6 months
C) 5 * 7/13 months
D) 11 * 1/13 months

Trick:      D/(A1/A + B1/B + C1/C)
               =6/(10/40 + 10/60 + 10/80)
               =6/(1/4 + 1/6 + 1/8)
               =6/{(6+4+3)/24}
               =6/(13/24)
               =(6*24)/13 = 11(1/13) (Ans.)
