- 8 men 1 day work=1/25
1 man 1 day work=1/25*8
10 men 1 day work=10/25*8=1/20
16 boys 1 day work=1/25
1 boy 1 day work=1/25*16
20 boys 1 day work=20/25*16=1/20
so 10 men and 20 boys 1 day work=1/20+1/20=1/10
Ans:- 10 days

- 8m=16b
m=2b -(1)
(16b*25)/w=x*(10m+20b)/w
10m=20b from (1)
x=10
w is same so it can be cut piece of work is same - 10 years agoHelpfull: Yes(1) No(0)
- (m1*b1*d1) / (m1b2+m2b1)
- 10 years agoHelpfull: Yes(1) No(0)
