Answer: E = 1.4
Explanation:-
1 is for the first shopkeeper and 2 is for the second shopkeeper.
C.P 1 = Rs 700
C.P 1 = Rs 700
discount% 1 = 30% and 6%
discount% 2 = 20% and 16%
S.P = C.P 1 - 30% * C.P 1
=rs 700 - 30% * rs 700
= rs 490
S.P 1= S.P - 6% * S.P
= rs 490 - 6% * rs 490
= Rs 460.6
S.P 3 = C.P 2 - 20% * C.P 1
= rs 700 - 20% * rs 700
= rs 560
S.P 2= S.P - 16% * S.P
= rs 560 - 16% * rs 560
= Rs 470.4
Total discount % 1 = (C.P 1 - S.p 1)/ C.P 1 *100%
=( rs 700- rs 460.6)/ rs 700 * 100%
=34.2%
Total discount % 2 = (C.P 2 - S.p 2)/ C.P 2 *100%
=( rs 700- rs 470.4)/ rs 700 * 100%
=32.8%
Total discount % 2 > Total discount % 1
Difference in discount =Total discount % 1 - Total discount % 2
=34.2% - 32.8%
=1.4%
Therefore , the first shopkeeper who offers 30% and 6% discount offer better 1.4 % more discount rate than the second shopkeeper who offers 20% and 16% discount.
