WE CAN SOLVE IT WITH ANOTHER METHOD
COST OF EACH PEAR = 1.90 $
SELLING PRICE OF EACH PEAR = 2.50 $
PROFIT = SELLING PRICE - COST PRICE (EACH PEAR)
= 2.50 - 1.90
PROFIT ON EACH PEAR = 0.6 $
NOW WE CAN EASILY FIND THE PROFIT OF 100 PEARS
PROFIT OF 100 PEARS = 100 X 0.6 = 60$
Number of pears =100
cost of one pear when he bought = 1.90$
total cost when he bought 100 pears = 1.90$*100 = 190$
selling price of one pear = 2.50$
selling price of 100 pear = 100*2.50$ =250$
His profit = selling price- total cost = 250$-190$ = 60$
So he is having 60$ profit
TOTAL PEARS =100
COST PRICE OF EACH PEAR = 1.90$
COST PRICE (CP) OF 100 PEARS = 1.90 x 100 = 190$
SELLING PRICE OF EACH PEAR = 2.50$
SELLING PRICE (SP) OF 100 PEARS = 100 x 2.50$ = 250$
PROFIT = SP - CP
= 250 - 190
PROFIT = 60$
