ans=4days
let x= 1 day work of 1 boy
let y= 1 day work of 1 girl
we get 2 equations:
6x+8y = (1/10) and 26x+48y = (1/2)
solving 2 equations give:
x=(1/100) and y=(1/200)
now, 1 day work of 15 boys and 20 girls = 15x+20y= (1/4)
thus, total days taken = 4 days.

swastik  (10 years ago)

so easy...
6boys+8girls=10days eq1
26boys+48girls=2days

so by simplifying
10(6boys+8girls)=1day
2(26boys+48girls)=1day

so 60boys+80girls= 52boys+96girls
solving above we will get 1boy=2girls

now put it in eq1
so it will be 12girls+8girls=10days
20girls=10days
den 15boys+20girls which is equal to 30girls+20girls will do it
20*10/50=4days

eqution 1 is 6x+8y=1/10
2nd is 26x+48y=1/2.
so x=1/100 and y=1/200
then
x=15*1/100
y=2*1/200
answer=4 day

(6B+8g)10=(26B+48W)2
=>
60B+80g=........
15*4B+20*4G=...... //divide from 2 , 2 times and 15 from 60

(15B+20G)4=......

it means 4 days
