THANKS FOR THE QUESTION !

ANS :

....................... 245 .......................

_____________________________

IN A SHOP :

=> THE RATIO OF NO. OF APPLES TO PEAR ;

=> 7 : 5

______________________________

LET,

=> X BE THE COMMON MULTIPLE OF THIS RATIO

_____________________________

NO. OF APPLES :

=> 7 * X

=> 7X

______________________________

NO. OF PEARS :

=> 5 * X

=> 5X

______________________________

CONDITION :

=> EVERY DAY :

=> 30 APPLES & 25 PEARS WERE SOLD

______________________________

LET,

=> THE DAYS IN WHICH SELLING OCCUR :

=> Y

______________________________

REMAINING NO. OF FRUITS :

APPLES :

=> 35

PEARS :

=> 0

______________________________

IN Y DAYS ,

APPLES SOLD :

=> 30 * Y

PEARS SOLD :

=> 25 Y

______________________________

FROM INFO ,

=> NO. OF PEARS - PEARS SOLD = 0

=> 5X - 25Y = 0

=> X - 5Y = 0

=> X = 5Y ................... 1

______________________________

FROM INFO ,

=> NO. OF APPLES - NO. OF APPLES SOLD = 35

=> 7X - 30Y = 35 .................. 2

______________________________

PUT X = 5Y IN THIS EQUATION ,

=> 7 ( 5Y ) - 30Y = 35

=> 35Y - 30Y = 35

=> 5Y = 35

=> Y = 35 / 5

=> Y = 7

______________________________

PUT Y = 7 IN EQUATION 1

=> X = 5Y

=> X = 5 * 7

=> X = 35

______________________________

TO FIND ;

=> NO. OF APPLES :

______________________________

NO. OF APPLES IN THE STORE :

=> 7X

=> 7 * 35

=> 245
