A Consumer buys 100 units at ₹ 5 per unit `P.e_(D) is 2`. At what price will the consumer buy 140 units of the commodity ?

Explanation

The formula will be
`{:(P" " 5),(P_(1)" "?),(overlineunderline(DeltaP" "?)):}" "{:(Q" "100),(Q_(1)" "140),(overlineunderline(DeltaQ" "40)):}`
`P.e_(D) = P/Qxx(DeltaQ)/(DeltaP)`
`(-)2=- 50/100xx(40)/(DeltaP)`
` DeltaP=-1 " " or Deltap=P_(1)-P`
`-1= P_(1)-5`
`-1+5=P_(1) or P_(1)=4`
