Question

An item was sold for Rs.152 at a loss of 5%.what is the cost price? In how many years will Rs.3600 amount to Rs.4320 at 8% per annum simple interest?

Answer 1

CP=100/100-5*152=100/95*152=160
hence the cost price is 160
SI=4320-3600=720
SI=prt/100
720=3600*t*8/100
720*100=8t*3600
t=720*100/8*3600
t=2.5years
