LET CALLS MADE BY FEMALE =X
CALLS MADE BY MALE =2500-X
LET SUCCESS RATE WITH MALES = Y/CALL
SUCCESS RATE WITH FEMALES = 2Y/CALL
ORDERS FROM FEMALE CALLS = X*2Y=480.................1
ORDERS FROM MALE CALLS = (2500-X)Y=360...................2
EQN.1/EQN.2
2XY/(2500-X)Y=480/360 = 4/3
3*2X=(2500-X)4=10000-4X
6X+4X=10000
10X=10000
X=1000
HENCE 1000 CALLS WERE MADE BY FEMALES.
