d) 8%<\/p>\n\n\n\n
Sol:<\/p>\n\n\n\n
Increase in SP of an article = 15% <\/p>\n\n\n\n
Profit percentage change = 5% to 15% <\/p>\n\n\n\n
Calculation: <\/p>\n\n\n\n
A shopkeeper increases the selling price of an article by 15% <\/p>\n\n\n\n
Let the initial SP be 100, then later SP will be 115 (increased by 15%) <\/p>\n\n\n\n
\u21d2 New SP = (100 + 5)\/100 \u00d7 100 = 105\/100 \u00d7 100 = 105 <\/p>\n\n\n\n
Now on initial SP, he got 5% profit, <\/p>\n\n\n\n
\u21d2 5% profit = 5\/100 = 1\/20 Initial SP = 1 + 20 = 21 units, Initial CP = 20 units <\/p>\n\n\n\n
We have assumed that initial SP as 100, <\/p>\n\n\n\n
\u21d2 21 units = 100 <\/p>\n\n\n\n
\u21d2 1 unit = 100\/21 <\/p>\n\n\n\n
Initial CP = 20 units = 20 \u00d7 100\/21 = 20\/21 \u00d7 100 <\/p>\n\n\n\n
For later he noticed 15% profit, <\/p>\n\n\n\n
\u21d2 15% profit = 15\/100 = 3\/20 <\/p>\n\n\n\n
Later SP = 3 + 20 = 23, Later CP = 20 <\/p>\n\n\n\n
Later SP is 115 as we have assumed, <\/p>\n\n\n\n
\u21d2 23 units = 115 <\/p>\n\n\n\n
\u21d2 1 unit = 115\/23 = 5,\u00a0 Later CP = 20 units = 20\u00a0\u00d7 5 = 100\u00a0\u00a0<\/p>\n\n\n\n A shopkeeper increases the selling price of an article by 15%.
