A team miners planned to mine 1800 tons ore during a certain no. of days. Due to technical difficulties in 1/3 of the planned no. of days, the team was able to achieve an o/p of 20 tons of ore less than the planned o/p.To make up for this , the team overachieved for this rest of the days by 20 tons. The end result was that the team completed the task one day ahead of time. How many tons of ore did the team initially plan to ore per day?
a)50 tons
b)100 tons
c)150 tons
d)200 tons

• U have to do it by x but u can make it a bit simpler for ur easy calculaions
  let they take 3x days to complete the work and y tons per day
  so 3xy = 1800 => y=600/x
  
  so the equation stands x(y-20) +(2x-1)(y+20)=1800
  substituting x by y u will get x as x
  
  so value of y will be 100
  
  I feel thats the shortest way out
