(b) 29.16

(c) 30.12

(d) 32.65

(e) none of these

  25*8% = 2/- 25+2= 27
  27*8% = 2.16/- 27+2.16 = 29.16 /-

• 8 years agoHelpfull: Yes(3) No(0)
• 1.5%+6.5=8%
  p(1+r/100)^2
  25(1+8/100)^2
  29.16

• total percentage increase= 1.5%+6.5%=8%
  after 1 year cost will be=(8%of 25)+25=27
  So, after 2 year cost of paper will be=(8%of27)+27=29.16
