Question

find the rate of discount being given on a mini toy gun whose selling price
is rupees 345 after deducting a discount of rupees 30on its marked price

Answer 1

Total money for toy=375
discount=30
cost with discount=345
345*100÷375=92
rate of discount=100-92=8%
HOPE THIS HELPS

Answer 2

let the discount% be x.

M.P = 345 X 100 upon (100 - x)

= 34500/100 - x

x = 30 upon [34500/100 - x] X 100

x = 30/[34500/100 - x] X 100

x = 30/345/100 - x

x X (100 - x) = 30/345

100x - x^2 = 30/345

x - x^2 = 30/345 X 1/100

x = 30/34500






uhh.... I think I did a mistake... sorry!
