Step-by-step explanation:
let CP of the article = x
at 5% gain, SP of article = x + (5/100)x = 1.05x
at 5% loss, SP of article = x - (5/100)x = 0.95x
given that 1.05x - 0.95x = 16.5
⇒ 0.1x = 16.5
⇒ x = 16.5/0.1
⇒ x = Rs. 165.
The cost price of the article is Rs. 165.
A full strip and a half of staples = 1 strip + 0.5 strips = 1.5 strips
1.5 strips = 315 staples
Divide both sides of the equation by 1.5 to find out how many staples are in one strip:
1.5 strips ÷ 1.5 = 315 staples ÷ 1.5
1 strip = 210 staples
Now halve both sides of the equation to find out how many staples there are in half a strip:
1 strip ÷ 0.5 = 210 staples ÷ 0.5
0.5 strips = 105 staples
Therefore, there are 105 staples in half (0.5) a strip.
