During a fair reeta gains rs 2 on each pen and loses rs 1 on each pencil she sells 50 pens and somepencils losing rs 15 in all how many pencils does she sells

solution:

gain on each pen = 2

and loss on each pencil= 1

gain on 50 pens = 50 x 2 = 100

let the number of pencils she sells be x.

amount of money lost on x pencils = x

net loss = 15rs

x -100 = 15

x = 100+15

x = 115

so, total number of pencils = 115

ian gonna lie that is way to much
