Answer:
60PENS
Step-by-step explanation:
PROFIT BY SELLING ONE NOTEBOOK = RS.6
LOSS MADE BY SELLING ONE PEN = RS 4
PROFIT MADE BY SELLING 30 NOTEBOOKS = RS 180
LOSS SUFFERED = RS 100
LOSS MADE BY SELLING PENS = 180-102 =RS 78
THEREFORE,NUMBER OF PENS SOLD = 78/4=19.5 PENS(ANSWER)
NO. OF NOTEBOOKS SOLD IN THE NEXT WEEK = 40
PROFIT MADE = 40*6 = RS 240
IT IS GIVEN THAT NO LOSS OR GAIN HAS BEEN MADE SO,
NO. OF PENS SOLD = 240/4 = 60 PENS(ANSWER)
