Question

a reduction of 15% in the price of wheat enable swati to buy an extra 3kg of it for 300 rupees. find the original rate and reduce rate per kg​

Answer 1

Answer:

Step-by-step explanation:

let the original price be = 15x

new price = 15x X 85/100   = 12.75x

300/12.75x - 300/15x = 3

300 [15 - 12.75 / 12.75 X 15 X x] = 3

300 [2.25 / 191.25x] = 3

100 x 2.25 = 191.25x

x = 225/191.25

x = 1.176
