      1 .    
      Answer : Option A
      Explanation :
      Avg price of onion in March = $1over 4$ x (16 + 24 + 32 + 40) = Rs.28 per kg

      Avg price of onion in April = $1over 4$ x (16 + 32 + 48 + 36) = Rs.33 per kg

      Avg price of onion in May = $1over 4$ x (8 + 24 + 40 + 56) = Rs.32 per kg

      Avg price of onion in June = = $1over 4$ x (8 + 16 + 48 + 56) = Rs.32 per kg

      AVg price of onion in July = $1over 4$ x (24 + 32 + 48 + 56) = Rs.40 per kg

      Avg price of onion in Aug = $1over 4$ x (32 + 40 + 48 + 56) = Rs.44 per kg

      2 .    
      Answer : Option A
      Explanation :
      Average price of onion in Gurgaon = $1\over6$ x (40 + 56 + 56 + 48 + 48 + 56 + 40) = 49.33/kg

      Average price of onion in Faridabad = $1\over6$ x (32 + 16 + 24 + 16 + 24 + 56) = 28/kg

      Average price of onion in Noida = $1\over6$ x (16 + 32 + 8 + 56 + 48 + 48) = 34.66/kg

      Average rate of onion in Ghaziabad = $1\over6$ x (24 + 48 + 40 + 8 + 32 + 32) = 30.66/kg

      Thus the maximum average price is in Gurgaon.
      3 .    
      Answer : Option C
      Explanation :
      Total sale of onion in June = 500 x $15\over 100$ = 75 tonnes

      Total sale of onion in July = 500 x $12\over 100$ = 60 tonnes

      Total income in a month = (average rate that month in all cities × total quantity)

      Total income in June = 32 × 75 × 1000 = `2400000

      Total income in July = 40 × 60 × 1000 = `2400000

      Reqd difference = 2400000 – 2400000 = 0
