Solution
- Earnings of Satish for looking after one goat for 1 day = Rs.1
It is given that Satish looks after 17 goats of the village in a day.
∴ Earnings of Satish for looking after 17 goats for 1 day = Rs 1 × 17 = Rs 17
Number of days in 1 month = 30
Earnings of Satish for looking after 17 goats for 1 month
= 30 × Rs 17
= Rs 510
Working:
30
× 17
210
300
510
Thus, Satish will earn Rs 510 in one month. - Satish’s mother has to pay Rs 5,000 every month for the loan.
Thus, Satish does not earn enough to help pay the loan every month. - Number of months in 1 year = 12
∴ Earnings of Satish for looking after 17 goats for 12 months
= Rs 510 × 12
= Rs 6,120
Working:
510
× 12
1020
5100
6120
Thus, Satish will earn Rs 6,120 in one year for looking after 17 goats.
