उत्तर
Let the M.P. be Rs. x
Second discount
S.P. = `(1 - "d"_1/100)(1 - "d"_2/100)(1 - "d"_3/100)` of M.P.
= `(1 - 20/100)(1 - 20/100)(1 - 20/100) xx x`
= `(80)/(100) xx (80)/(100) xx (80)/(100) xx x`
= 0.512x
Clearly, since 0.512x > 0.510x, so, the S.P. of the first is less than that of the second
So, the first offer is better than the second offer.
