Question

a shopkeeper buys 80 articles for rs 2400 and sell them for a profit of 16%. find the selling price of 1 article

Answer 1

sp = cp × (100+p%)/100
sp=2400×116/100
sp = 24× 116
sp = 2784

so 80 articles = 2400
1 article = ?

so 2400/80
= 30=sp

Answer 2

CP of 80 articles= Rs 2400

Profit%= 16%

Profit amount =16/100×2400

= Rs 16 ×24

= Rs 384

SP = Cost Price + Profit

SP of 80 articles= Rs 2400+384

= Rs 2784

SP of one article= Rs 2784/80

= Rs 34.8

SP of one article is Rs 34.8

Therefore SP of 1 article is Rs 34.8
