Question

A ने b को एक रेडियो 10% की हानि से और B ने c को 20%लाभ से 891रूपये मे बेचा तो A ने उसे कितने मे खरीदा था?​

Answer 1

Answer:

suppose that A buy the radio in Rs.x

then,

A sold the radio to B in 10% loss.

or B purchase the radio in 90x÷100.

then B sold the radio to C in 20% profit

20% of 90x÷100 is 90x÷100+ 20x÷100

And B sold the radio to a in RS.891

so directly

90x÷100 + 20x÷100 = 891

after calculating we will find X = 810

so the initial rate of radio is Rs.810

Answer 2

Answer:

90×÷100 + 20 × ÷ 100 = 891 slove it
