ANSWERS:

1. The weight of Manu = 22 kg
   Total weight of 12 such children = 12 x 22 = 264 kg.
2. Speed of the log boat = 6 km/hour.
   Time taken to cover a distance of 30 km = 30/6 = 5 hours.
3. Speed of the speed boats = 20 km/ hour.
   Distance travelled in 5 hours = 20 x 5 = 100 km
   Distance travelled in half hours = ½ x 20 = 10 km
   Therefore distance travelled in 5 and half hours = 100 + 10 = 110 km.
4. Speed of Motor boat = 20 km/ hour.
   Time taken to cover 120 km = 120/20 = 6 hours.
   Time taken to cover 5 km = 15 minutes.
   Time taken to cover 125 km = 6 hours 15 minutes.
5. Speed of a long tail boat = 12 km/hour.
   Distance can travel in 8 hours = 12 x 8 = 96 km.
6. Savings in each month = Rs 375
   Savings of 20 fisherwomen = 375 x 20 = Rs 7500.
7. Money spends on prawns = ¼ of 500 = Rs 125
   Money spends on kingfish = ¾ of 500 = Rs 375.
8. Money paid back in every month = Rs 425
   Money paid back in one year = 525 x 12 = Rs 6300.
9. Amount paid back in one year = Rs 38400
   Amount paid back in every month = 38400/12 = Rs 3200.
10. To get 4 kg dried fish, we need 12 kg fresh fish.
