Solution:

Ratio of work done by 20 men, 30 women and 36 children

=20 × 3: 30 × 2: 1 × 36

=5: 5: 3

Wage of 20 men

=\;{5}/{13} × 780=300

Wage of 1 man

=300/20=15

Similarly, wage of 1 woman = 10
And wage of of 1 child = 5
Total wages of 15 men,21 women and 30 children for 2 weeks

=2 ×(15 × 15+21 × 10+30 × 5)

=2(225+210+150)

=2 × 585

=1170
