Question

Satish is a 13-year-old boy. His father had taken a loan for farming. But the crops failed. Now Satish’s mother has to pay Rs 5000 every month for the loan.

Satish started working — he looked after 17 goats of the village.

He earns Rupee 1 every day for one goat.

• How much will he earn in one month?
• Does he earn enough to help pay the loan every month?
• How much will he earn in one year?

Answer 1

• 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.
